This thing is tough

Just returned from 2 hard weeks in Africa and my only bag was the 45L Black Hole MLC. It easily held all clothes, shoes, etc., even when loaded with gifts I returned with. I mostly used the shoulder strap but the backpack straps also work really well. Easy to put in the airline overhead bins. This thing is tough - held up perfectly, kept my stuff d...

Perfect Travel Bag

I bought this bag to use as a travel bag. So far, I have used it on a couple of trips. It holds enough for me to take a week long trip. The organization that it offers is second to none. I love the Black Hole line from Patagonia. This is my third bag from that line. I have a 65L duffel and a 32L back pack that have taken plenty of abuse over the ye...

Patagonia MLC suitcase

I love the organizational ability of the suitcase. This is the second one I've had and now I am retired and stepped out to do more leisure traveling. There is one small tweak I would suggest as I am 5'4" . I am trying how to figure a waist belt on this. The shoulder straps are great, but when I fill this carry on bag (no checked in l... Read Moreuggage), it becomes way cumbersome. I switched on a trip to a backpack with a waist strap with the same items and weight, no problem. But with the MLC, it was digging into my shoulders. The weight could be better distributed if there was a waist belt. More weight can be carried on the hips versus the shoulder. BTW, with the airlines losing luggage as such a great pace, I was thrilled with the content capacity and then learned the hard way, shoulder straps alone isn't the way to go. A method to add one on or a new design MLC would go a long way. Thank you for making great products, I also use your flyfishing gear.

Great One Travel Bag

They have a 2022 version that made some changes to the bag. Some I think for the better and some not. This is a great bag. Not as shiny as I worried it was going to be. Overall nice look. Very functional. Plan to use on long overseas trips. One problem I solved was the lack of a belt strap, so I ordered one from Tom Bihn that fits perfectly. The ba... Read Moreg has a great amount of pockets to store everything in one bag. No more rolling carry-on and backpack. The only thing missing is cinch straps but not worried. I like the pocket design on this bag more than the new design. Both look great but I decide to grab one of these while I still could. Might try to grab a Mini 26L as well.

Great travel bag

Perfect for a weekend trip

great travel carry on

I ordered this bag as well as a top rated one from another company to compare and this bag was far better (and a bit cheaper). I love the red color and that it has so many different carrying options, though Ive only worn it as a backpack so far. I got this for my 5 week trip to Europe since I didnt want to deal with a roller bag or checking luggage... Read More and it fit all of my clothes, toiletries, and books with a little room to spare. I did put my laptop and iPad in a separate tote because the laptop slot didnt strike me as the most padded, but thats my only small complaint. I love all the internal organization and how many different pockets there are, it made it really easy to remember where Id put everything as well as taking liquids out at security etc. Easily fits in the airline carryon measure thing (at least for American). Would definitely recommend for anyone looking for a lightweight and convenient travel bag. Love the way it looks and feels too!

Perfect for Backpacking Thru Europe

My sons loved this bag for his semester abroad. It's perfect as a carry on or a backpack for taking off on the weekends. Rosehip is a great color too.

August 30, 2022

Great bag, but needs a couple features.

I've taken this traveling all over for a year or two. It is rugged and sturdy. But this bag needs a hip belt and a little more structure or compression straps. If it's full or has a laptop, it's too heavy on your shoulders for proper long walking. If it's not full, then it feels floppy and could use a built in strap. It looks li...

They thought of everything

Purchased the the 45L. They thought of everything when they designed this bag. Perfect amount of pockets.

My second one!

This is my second MLC. I used my first one as an overnight bag and then my son borrowed it and I never saw it again. I now use my second one for traveling and as an overnight bag. I can't believe everything fits in it. I'm a short (4'11") woman and the straps are adjustable enough for me to always find a good fit.

Everything I own from Patagonia is outstanding. Holds up for ever.

Great for One Bag Travel

The bag is the right bag to travel in if you don't want wheels and need a bag to stuff full. A great weeklong bag that could easily stretch into months if you packed right.

I am enjoying the bag,

I am enjoying the bag, as I can stuff it under airplane seats. The only thing I would suggest you make note of for further product engineering is that the fabric inside of the zippers can easily get pulled in upon opening.

Most amazing backpack invented

Id like to see you find something better. The pickets on this are amazing and you can stash just about anything. The whole thing packs down nicely and keeps me organized while traveling. True quality!!

Love this bag!

Really versatile. Normally I lean toward big open sacks with no frills, and this isn't that. Heaps of organizational compartments available here -- some I've used; others, not yet.

International Travel made light and agile

Room for absolutely everything I needed for 7 days of busy sightseeing in Spain. More than enough room for 5 outfits, toiletries, tech needs, accessories, and space four souvenirs to come home. Definitely easily fit into all airline spec racks due to flexible sides and not overpacking. Wish it had a water bottle pocket but many loops on backpack... Read More straps or front panel to attach a bottle via carabiner. Used 2 packing cubes in the main compartment to compress clothing and keep the bag as spacious as possible. Comfortable for carrying luggage around, agile for getting on and off planes and trains - so much better than a roller bag for traversing old cities full of cobblestones and stairs, which were common on my trip. I really loved how independent and agile this bag made me feel, traveling solo. Highly recommend free videos on packing light for Europe from Sarah Murdoch online - those tips + this bag made for a wonderful, memorable trip with just 13lbs of cargo.

Perfect Size - Airplane Carry-On

I purchased the MLC Backpack 45L for my son who was doing some traveling after completing his graduate studies. He loves the bag! So stylish, and well thought out. Perfect for an airplane carry-on. Lots of compliments. Great gift idea.

great carry on but super large

There are two of these bags, the MLC 26 vs MLC45, I really think that patagonia should have something else in the middle. Love the pockets and interior compartments.

Floppy sticky bag

Sadly the Black Hole lacks structure to carry well unless it is fully loaded. With a small load it becomes a floppy bag on your back.

I've used this bag now for 9 months, making two international trips and several domestic for both work and play. I am constantly impressed with how much I can pack.

Patagonia Black Hole® MLC® Briefcase Backpack 45L

I purchase this for a two-week trip to Morocco. I was looking for luggage that I would not have dragged behind me. It was great to grab and go. It has various straps to use as a backpack or shoulder bag, and two handles to grab it vertically and horizontally. It also has a built-in luggage tag. Surprisingly it holds a good amount with ample pockets... Read More, more than I used. I ended up checking the bag since I did not want to deal with overhead; it may not be the bag for overhead, but that will be for my next trip. The two caveats are that it is bulky and can become heavily loaded. Then having dragged wheeled luggage over the rattle of cobblestone streets, up and down stairs and escalators, and over hundreds of curbs, the Black Hole made traveling sweeter.

The ultimate organizer

This bag is amazing. From the variations of carrying methods to the many sizes of organization pockets.

Great bag! I used this for a quick weekend trip, and really like it. Plenty of room, lots of storage, and zippered compartments, to keep items where you want them.

I just got back from a 5 day work trip and used this pack as a carry-on so I didnt check luggage.

Lots of pockets

I was looking for a carry-on bag for a recent trip to the UK. I decided on the Patagonia Backpack Brief case after much research.

Not right for me

The bag is exceptional in its quality. If I needed it for an overlarge computer tote bag; then I would be thrilled. I ordered the bag for its multiple pockets and shoulder strap.

Best Bag Ever for Single Bag Travel

An amazing bag. Everything I expected and wanted. I had my eye on this bag for a little over a year after seeing one at REI, but was holding off on purchase due to the price point.

Pefect Carry On

I bought this for short trips and it has worked out perfectly. I love that it has a sleeve on the back that slides right on to the handle of virtually any rolling luggage even though I haven't flown anywhere since the pandemic started, I can't wait to try it.

Great bag. Amazing service.

Love the size and weight of this bag. Super light, holds a ton and fits into an overhead bin. Even better, I messed up on the timing of my shipment. Customer service went above and beyond to make sure I got it before my trip, after the fact, even though it was totally my fault. Super impressed with the quality and service of Patagonia.

Great luggage for leisure travel and work

Now I have three pieces of the luggage set. This MLC in the 45L is awesome. I have a black hole duffle, and a brief case, and use these pieces regularly. They organize my life, are tough, they perform, and are just "sexy" to tote around.

Great Travel Bag

The Blackhole MLC Backpack 45L is a great travel bag. I had an earlier version that I used for business and personal travel for 20 years before it finally wore out (after replacing several zippers and sewing up rips).

Definitely a great bag/pack.

Super Versatile and Durable

I love that it has multiple forms of storage for minimalistic travel. The waterproof material is great for many experiences. The different handles are great as well. Can't wait to travel the world with this bag. Perfect for one bag travel.

I live on the road, and this bag has been perfect since I got it two weeks ago. I like all the pockets the have nicely fit power cords, snacks, sunglasses, etc. It's handy to put on as a backpack when it's time to move, and I think the colors are cool. I'm very happy with this bag!

May 24, 2021

Prefer the 40L duffel

I used one of these while bouncing around Asia for a few months before ultimately living out of it in Spain. Being Black Hole, the material is great. But the backpack straps are terribly uncomfortable, position the weight uncomfortably on the one's back, and seem ready to break off the bag. When the bag isn't full, it loses its rectangula... Read Morer shape, looking droopy (if visual appeal matters to you). When full, getting anything out of the side pockets is difficult. If you can do with 5L less, I'd recommend the 40L Black Hole duffel. I've been living out of it for 8 months now, feeling I've made a stellar purchase. The straps are great and it doesn't put stress on my back.

Perfect carry on

This is my second Blackhole MLC and it lives up to its name. I can fit everything I need to carry on and is rugged enough to handle the harness of working abroad and constantly traveling around the world.

Perfect for Traveling

This bag was recommended to me by someone who travels frequently and doesnt like to check bags, but packs quite a bit for work. The recommendation was spot on! It fits all of my work equipment and everything I need while traveling to avoid having to check bags. Its also durable and stylish.

Great travel bag that doesn't need to be checked in. Wish it had a space for running shoes so you wouldn't have to put them into your clean clothes section. That's the only space they'll fit into.

great bag--plan to use it for years

Well, I bought this during the pandemic and haven't yet the opportunity to travel... but I checked it out thoroughly upon delivery and it is going to be awesome. I anticipate using it for all sorts of trips and I know it will last a long time. I love it and look forward to using it.

The perfect carry on

This is the perfect size for a carry on. Has so many useful pockets- Patagonia thought of everything. Use alone for a short trip or pair with a bigger bag for international travel! Now I just have have to wait for travel to be a reality again! ;)

February 25, 2021

Rugged build.

The pocket lay out is great for my uses. Long Weekend trips. Able to keep things organized and snug. Overall build is stout , you feel it in the zipper. 17 mo old loves fastening the chest strap too.

Great carry-on bag

Just used this bag as my carry-on for a Western ski trip. I take everything I need to ski (minus the skis) on my person so I can still go out even if my checked bag goes missing. I was able to carry my ski boots, knee brace and full ski outfit along with an iPad and a few casual clothes without over-stuffing the bag. It fit easily into all overhead... Read More bins including the narrow Canadair Jet. I was never asked by the flight crew to check it plane side. The MLC has many well designed storage options to help organize your stuff. Im very happy with the bag and would buy it again without hesitation.

Great bag, tacky logo

This is a fantastic bag for travel and an improvement over the previous bag. The only thing I don't like is the size of the logo. I get you to want to brand your product but this is too much and takes away from the aesthetics of the bag.

February 9, 2021


Totally jazzed with this bag. Now I can put my ski boots in them, and know they'll arrive with me. Pockets and zippers are numerous and flexible in use.

Great bag, I feel made for taller people

I took this bag across Europe for 6 months and it withstood spills, cargo areas of planes, beach, mountains, scratching / dragging on dirt/rocky road. No holes, no rips, spills, leaks, malfunctioning zippers. This bag is 100% adventure ready. The only downside is that as my bag was filled with gear, it got a bit heavy and there was no waist strap ... Read Moreto help me redistribute the weight, resulting in the whole bag resting on my shoulders and become very uncomfortable, resulting in my the dragging bag down the road (it withstood that abuse). The proportion on the bag to my height of 62inches, the bag went from top of my shoulders to the middle of my butt. This I feel was the only downfall of the bag, but other than that it's a solid bag.

Perfect Burly Travel/Daily Bag

Just returned from Baja...Perfect for four flights, vans, trucks, and serious beach use. The multiple zipped compartments held kite gear, foil tools, parts, water, sunblock, fins, towels, iPad, etc. Such a great purshase.

Black Hole Mlc Backpack

This is my favorite Patagonia backpack! They are so easy to sell, because they are so well designed. The amount of space and the ability to organize makes living out of this bag a breeze!

Laptop sleeve is wasted space

This is a great travel bag (if you are a light packer). The one thing I hate about it is the laptop sleeve - big waste of space. I don't take a laptop on trips and even if you do, the laptops sleeve is GIANT. I can fit a jacket and two pairs of pants in the sleeve easily but i would rather that the pack just didn't have the laptop sleeve ... Read Moresection. Because of its pocket-like shape, it's not a good way to pack for clothing. Get a neoprene sleeve for your laptop and put it in the front pocket already.

Best Bag EVER!

Im a medical provider, working night shifts in rural Midwest hospitals and ERs. In the past, Ive had to carry 2-3 bags with all of my clothes and gear for a stretch of night shifts.

Best travelling backpack!

Best travelling backpack! I've received this as a birthday present and I'm totally in love with it! It's really comfortable to carry as backpack, also convenient to carry on a shoulder and it fits well on top of a wheeled suitcase. It's super light and fits perfectly on overhead lockers on plane. It's perfectly organised w... Read Moreith plenty purposed built zipped compartments, which are great to pack and divide clothes, from electronics, books and magazines. This allows keeping everything tidy even during a week-long trip (in the past I had to unpack and repack everything almost on daily basis) and being able to find where everything is! The front pocket is great to keep small items, such as passport and wallet for quick access and the side/ back compartment is perfect for storing a laptop. The only down side is that it doesn't have an external pocket for a water bottle, which looks like could fit on one of the sides (hopefully Patagonia can add this to future models!). It's also waterproof and made 100% in recycled fabric (love Patagonia!). Can't wait to take this backpack to the next trip :) Last, but not least, big thanks also to the guys working in Trento (IT) store for their expertise and friendliness.

September 2, 2020

Useful carry on. Fits overhead bin without drama.

Not too heavy, but well divided to keep items organized. Laptop sleeve saves trouble passing airport security. Fits 16" Dell Mobile Workstation, older and bulky, with big screen borders. Zippers are robust where needed and smaller in low stress areas.

August 21, 2020

Best carry on!

I originally got this bag for a trip before the global pandemic derailed all plans. I've used it twice for domestic flights and it's literally a black hole. I can fit multiple pairs of shoes, clothes for a week, a small dop kit, plus my laptop, a notebook, and all necessary chargers. With ample space comes weight and sometimes when on my... Read More back it does get a bit heavy. It is great for walking through the airport but definitely not for extended carrying. I also wish it had an external water bottle holder. I pair it with a Patagonia Atom 8L sling that I wear on the front and it's a great combo!

July 7, 2020

Best Travel Bag, hands down

I have now traveled to over 5 countries with this bag. If you are looking to be able to carry on and pack a lot into your bag this is perfect for you. The only downfall is that it doesn't have an external water bottle pocket. This fits all of my camera equipment plus days of clothes and still I can walk onto a plane with it.

Versatile bag for travel

Love this bag

June 17, 2020

Cant wait to try it out

So I bought the MLC bag to travel lite overseas, however with COVID-19 I havent had a real chance to use it the way I intended to. I have however packed it with 2 sweatpants, 3 jeans, and 7 tee shirts and some underwear. It still had room for toiletries and small random stuff. Ill update my review when I do travel with it.

June 17, 2020

Super Versatile

Bought this bag to haul around my 16" MacBook Pro. Works perfectly for weekend trips when I want to pack light. Can fit about 3 days worth of clothes along with an 11" iPad and laptop comfortably

March 12, 2020

This makes the perfect carry on!!

This is the best carry on ever! I got so many compliments on it and I was able to fit more than a weeks worth of clothes in it, plus more! I defiantly am going to get another one for my significant other! Highly recommend! It fits in the overhead bin of small regional jets! You just have to push kinda hard and squish it down. I love it!

Near Perfect Design

I'm sure my review will get lost in the other numerous good reviews of this bag. I don't often write a review of a product so soon after purchase, but this bag was worth it. Pros: -Compartmentalization -Easily fits in overhead luggage of a plane, and not be that annoying person trying to shove a bag that clearly doesn't fit -Comfo... Read Morertable carrying configuration Cons: 45L might be a bit large for a shorter person and all around use, and the only other option is a 25L MLC, which may be too small for travel, and daily activity.

January 15, 2020

Awesome plane bag

Great for work trips, easy to carry, easy to organize. Fits in the tiny overhead compartments for regional jets if you don't mind squishing it.

Better than expected

I travel a lot for work and have been using a 60L black hole duffel for about 5 years now. I love the black hole but it just wasn’t compartmentalized enough. The MLC45 is perfect.

Almost perfect!

For years I've traveled with the Black Hole 40L Duffel. Able to fit 2 weeks of clothes and necessities and small enough to never have to check it when flying. My only gripe about my 40L duffel was that I had purchased it years before the backpack straps were added. I always wished mine had them because the shoulder strap is useless when boardi... Read Moreng and deboarding a plane; unless you want to be the guy smacking each isle-seat passenger on your way back to the cheap seats. The MLC 45L is SO much better! Smart, thoughtful compartments to divide all your stuff. 5 more liters of space and still carry-on compatible. A sleeve to connect to my wife's wheeled luggage and so many other added details. If you're a minimalist traveler and hate checking bags, this bag is excellent! My only gripe is that I think the zippered compartment that conceals the backpack straps when not in use is a waste of usable space since you cannot zip it closed when the straps are out (Which mine always are). I'd have like to have seen removable backpack straps that were mounted on the exterior like on my 70L duffel and that would allow you to use that large existing compartment to stow your straps when not in use but also as extra pack space when the straps are in use. Other than this apparent design over-ambition I think this bag is absolutely perfect. Dare I say the R1 of travel bags.

December 18, 2019

Black Hole MLC 45L

I've not used the bag yet, but planning to make a trek to Mexico for 2 weeks. There's plenty of room for everything I need to wear, place for 2 pairs of shoes, camera, passports, laptop, etc. So I'm excited.

December 17, 2019

No need to check in luggage with this travel pack. Fits perfect in overhead storage and easy to carry around the airport. Really like how organized you can keep items in this pack.

I travel for a living and wanted a “go bag” I could keep fully stocked so when work calls I can immediately hop on a plane with everything I need no checked bag required.

I especially love the outer zip pocket so I can keep wallet and passport close when passing through the airport but still secure.

I love the bag! Just one suggestion for improvement ...

I’m traveling with this bag now on a 10-day trip to Iceland & England. I love everything about the bag except one thing: I think it needs compression straps. I only brought this bag & a personal item, so everything I had for 10 days had to fit in this bag, and I had to buy a luggage strap to wrap around it so when I packed it full, it would... Read More still meet the carry-on requirements, which was sort of disappointing since it’s called the Maximum Legal Carry-On. Otherwise, it’s fantastic. I stayed organized; it has great pockets & compartments, but not too many; and it’s lightweight. Also, I love the shoulder strap, backpack straps & grab handles - it’s so easy to carry it different ways. I definitely recommend it since my one complaint is fix-able.

November 23, 2019

Awesome Flight Carry-On/Boot Bag

This a very well made and sturdy bag. My ski boots fit nicely in the main compartment with plenty of room for other necessities. The multiple carry options are a bonus. My favorite is the backpack option(leaves my hands free). Lost or delayed skis, gloves, and poles can be picked up at the mountain but my boots are irreplaceable.

November 21, 2019

Almost Perfect, with a Fatal Flaw

I've had several MLCs over the past 15 years, and while all were good bags, the latest iteration is the best. This said, there is one glaring flaw for frequent travelers--the bag only functions best when you pack it absolutely full. Although there are zippered compartments inside to organize things, there are no compression straps, inside or o... Read Moreut, meaning that if the bag is not full your clothes will slide and bunch up at the bottom (no matter how you are carrying it). I often travel exclusively with a carry-on, but rarely pack it all the way full, and the constant shifting and wrinkling is leading me to look for a new go-to bag. I don't want to buy a smaller bag, because I like the flexibility of having more or less space as needed. A couple of simple cinch straps on the outside would have made this bag perfect--maybe next generation? I can only hope.

November 19, 2019


I purchased this bag for a weekend bag that fits carry on. No issues at all with carry on requirements. I did get about 1 million compliments on it, including the pilot of the flight. Great bag Patagonia, great bag.

November 13, 2019

Better than a roller!

I've been traveling for years and refuse to use a roller bag as a carry-on, they are clunky and obnoxious. Was so happy to find this bag, which holds MORE than a roller, is structured by flexible and easy to carry right on my back.

These were such a great solution! We loved them so much we even bought a pair as gifts for our son and his wife for their honeymoon in Portugal in October and they love them as well for the same reasons as they were traveling for two weeks. The pockets/compartments give lots of options for best ways to pack. We packed "just enough" clothes and it wasn't too heavy or awkward and much easier than pulling a wheeled suitcase along.

Best duffle!

I love my black hole bags fits everything for a weekend away or a backpacking trip.

Bad shoulder strap

I bought this specifically for the shoulder strap but it’s been disappointing. The buckle to material design is bad. The shoulder strap simply comes undone and goes to full extension every time. I’ve tried to double it back in the buckle and it still failed. I’ve now going to stitch it down. The rest of the bag is great.

Found this great for a long weekend or as a compliment to a roller bag for extended trips. I love all the built in organization, something that is lacking from the black hole duffle. It’s a great carryon. I was able to fit it in all but the smallest of overhead spaces.

Surprisingly large, great organization, pack it full!

This bag is BIG! I've taken it for weekend travel trips as well as camping and it is plenty big. The downside of its size is that if it is not full, things tend to fall to one side and the bag becomes awkward. It would be great if there were compression straps and packing cubes could also help in place of straps. The shoulder strap is somewhat... Read More awkward if the bag does not have something inside to keep its shape, so I tend to use the surprisingly comfortable backpack straps. The main compartment access zippers are nice and big so they are easy to open. Inside the bag is split into two sides like a suitcase which is nice and ends up creating additional space for something rigid like a large laptop. The outside double zippers I find to be too small so they are difficult to unzip one-handed which may help with security but not convenience. There are tons of organizational pockets and the pass-through for a luggage handle works great. Depending on your airline and how strict they feel like treating you on your day of travel, I've gotten away with a 22" spinner plus my MLC under the seat (not packed full) for longer trips. I love the new matte finish on the Tres MLC 45L. Maybe in 20 years when this black hole wears out, I can get a new one :)

Last travel bag I’ll ever buy

I seriously love everything about this bag. Tons of pockets, laptop sleeve, backpack straps, quick access pockets, and maximum capacity.

Perfect do-it-all bag

I love this bag because it's big enough for an efficient packer to go on a week-long trip, but it's compact enough for shorter outings. It is an ideal carry-on size, and the straps are great if you have it loaded up.

August 12, 2019

Great for Storage...horrible to carry!

Fantastic pockets for organizing your things. The back pack straps are ok. The weight distribution on the pack is awkward. Very hard to carry with a 17" laptop and clothes for a week of work travel. It would be a fantastic pack if it would work more like a backpack.

August 10, 2019

Great size and very versatile

Good size for carry on and can pack a lot of stuff. Perfect companion to my Black Hole roller bag as this bag has a sleeve so it can rest on the roller bag handle.

Travel Worthy

I have used this case twice to travel out west in my teardrop trailer. It allows me to pack a week’s worth of clothing, electronic accessories and toiletries, towels, etc. so much space and different compartments to stash stuff. I am very pleased with it.

Not enough structure
