Ms Capilene® Air Bottoms

Kinda Large
June 16, 2022

Just kind of weird

I really dont know what to make of these. They are like baggy long underwear that I guess you can wear as tights if you want to? I recently used them on a 4 week bike tour and they did come in handy. I wore them as long underwear when it was chilly and slept in them a few times when the temps dropped. I guess people wear them as tights for hiking ... Read Moreetc. But I just cant see that. I think they would snag on everything. I think the wind would cut right through as well. They were certainly warm and comfortable but I cant see using them for anything other than sleeping or a base layer.

Lite and Warm

Warm even on a wet storm day.

March 22, 2022

Highly recommended is you can afford it

Hands down the best base layer Ive ever had. The waffle cone air construction traps heat when I need it, and vents it when I dont. With proper mid and outerwear integration and venting Im always at a proper temp snowboarding hard in the Rockies on runs that can exceed 3 miles. Excellent wicking. My only complaint is the price. I think 200 bucks for... Read More a set of Long Johns is a little excessive especially since on extended trips its hard to get by with just one. That being said I definitely notice a difference when I put on something else.

Superb fabric. No fly.

For me, no fly means no deal. Too bad, since otherwise the fabric and tailoring are excellent.

March 7, 2022

Warm and dry

I wore these once, totally forgot I was wearing them. Warm and dry and breathable. Everything you want. My pair seem to have extra space/volume in the lower leg (calf area). I would prefer it to fit more closely so it doesn't fold under a ski boot.

February 26, 2022

A good compromise between wool and Capiline

Call these my 'crepe' layers as that was my 1st impression of the texture upon receiving them. Originally, I had purchased five years ago the equivalent tops (w/hood) which were pure wool and bottoms made of only Capilene (the wool bottoms were sold out). After a 10 days of climbing in Chile, the Capilene bottoms started reeking, but th... Read Moree wool did not. (Mind you, it's always been the opposite when I've been out there past 7 days). The tops were perfect for mountaineering in that you can sweat, not freeze up, and not feel the hell of itching from damp wool. These were pure pleasure to wear on a cold, windy day. Capilene was also met the same goals, too, but smelling like a bum wasn't conducive to my fellow folk back at camp. Hoped to see offered online again and for whatever reason, they'd moved onto something else (That's Patagonia: let's try it and see what works). This year they offered them again as a mix and bought a couple of pair to see if they would endure my skin biology. Used them for 10 days straight at home and during my various local hikes (Chile was out due to Covid). Upshot: no intolerable smell. So per the title, I recommend these for comfort, warmth, and a sense of refinement and décor odor-wise after weeks without a shower.

February 25, 2022

Huge inconvenience factor

It's a great base layer, but when working outside in very cold weather wearing multiple clothing layers, the inconvenience factor is huge; your Men's Capilene Air Bottoms have no functionally fly opening! (At least, I was unable to find one). Who designs that sort of thing?

Response from Patagonia

Waders cold weather must

I use under my orvis wafer pants a must to keep me dry all day in cold 34-37 degree water

February 8, 2022

very warm, very light . . . but no fly!

I'm a small guy, 5' 9" and about 150 pounds. The small size I ordered is fine in waist, butt, thighs, but is a little long. Not the end of the world, actually. I was surprised that the garment labeled for men does not have a fly, however.

Response from Patagonia
February 9, 2022

We appreciate your feedback on the fit, sizing, fabric and features. For many reasons including focusing on fewer seams, our designers have chosen to forgo the fly on this garment. We welcome you to [return]( them if the design doesn't work for your purposes. Thanks for the review!

February 7, 2022

Nice for ice

I wasn't really sure how I would use these... they seem too light and airy to be warm, but too thick to be good for exertion. But they are both. I hiked a long approach in these in single digit F weather with deep snow and a heavy ice climbing pack, which had me sweating profusely. I had brought a Capilene Air hoody so I could swap out my swea... Read Morety approach base layer shirt, but was worried my sweaty Cap Air bottoms would freeze solid while I was belaying. Nope, they miraculously kept me warm all day and dried incredibly fast. I was astonished. These are now my go-to's for ice climbing. And I, for one, applaud the lack of a fly -- I have never in my life used one and never understood the point -- especially when wearing many layers. These have a double layer of material protecting your man parts, which makes much more sense to me. The fit is like old cotton waffle thermals, though... long and baggy. I normally wear large pants, but have been wearing medium capilene bottoms since the 80s, which work for me again here. And they do let more air pass through than a denser weave.

February 2, 2022

So warm

Warm, keeps moisture away from skin and very comfortable.

January 30, 2022

Step up from previous Air pants

I had the previous model, which have blown out in the crotch after much great use. This new 3D stitching is an amazing improvement and the fabric has more loft and density without creating too much heat. They are super comfortable with plenty of room. They actually run much longer than I expected but never notice the excess around my heels and the ... Read Morecrotch doesn't sag while still having plenty of flexibility. I do wish there was a better way to hang dry these, there is only a very small 1/4" loop. And these is now no front hole for relief, which is not a downside considering less material, better construction, and how many times I actually used it in the older model. Thanks for improving a beloved piece of clothing.

January 26, 2022

Skiing in comfort

Light weight. Breathable. High quality construction. Warm. Excellent for skiing when temperatures are in the teens & low twenties.

January 25, 2022

Just what is needed

I already own a pair and wanted a second for work to have a backup pair for when the others need washed.

January 24, 2022

Run large

I almost always wear a medium, Patagonia or o/w. These were way too long, a blessing for my son who is 6'3" (fit him perfectly). They felt luxurious for the few seconds I had them on, just long enough to realize they were too large. Just placed an order for the small.

January 19, 2022

great material, wonky sizing...

This material is terrific - everything one would hope for with a wool blend and advanced texturing. But the sizing is bizarre. I'm 6'4, 186 lbs. The *medium* fits in the waist, is a bit loose on the lower leg, and is actually a bit too long at the hem. Like, who is fitting these? I am hoping they shrink a touch to make them near-perfect,... Read More but I pity anyone who is under 6' and orders the size M - it'll be over their feet. (note: even in the modeled photos on people you can see how long these are, as they pile up at the ankles)

January 7, 2022

Balanced warmth

This winter has seen some highly variable ski conditions and these base layer bottoms have been great from -8° up to 37°. Warm when needed without being sweat inducing on the warmer days. Super light weight and very comfortable. Bonus - they don't get as stinky as previous capilene only base layers.

December 19, 2021


No fly. Can't take a pee without dropping your drawers. Try that with three layers on.

December 16, 2021

Best base layer

So light. So warm. So soft. So comfortable. Best base layer Ive ever owned.

December 13, 2021

Very good base layer

A bit pricey. They are a very good base layer . Comfortable, sizing is just right for me. Slender guy.

Men Beware there is know fly.

This warm long john would have been great...except there is no fly. Not sure what Patagonia was thinking. When it's 10 degrees out and I'm backcountry skiing and I need to find a tree, I guess I am supposed to pull everything down to my knees.

For nearly 20 years I have been watching my lw stretch capeline get thinner and thinner as I waited for Patagonia to make a product to work with me for tele skiing. ie not thick, and allow for the constant movement. finally.

Too bulky for very active winter outdoor activities.

I play outdoor hockey in Minnesota. The temperature is always below freezing and typically below zero.

October 20, 2021


I have purchased a lot of Patagonia gear specifically for the fit. Why would you change the sizing now? These things are long so they end up baggy at the ankle. I dont see myself wearing these with ski boot on. They are high hipped with no fly. Why would you not sewn a fly on these but kept it on other models? and with zero acknowledgement of its a...

Good fabric

These pants are good for biking when its cold weather

June 30, 2021

Deliciously comfortable, BUUUUT....

USE WITH CAUTION (I really shouldn't have to say that, but here we are). I received these in early February, and within the first week of owning them, a hole had already formed in the crotch, and another around the knee. These run BIG, so these holes weren't due to a tight fit (and even if they were, I would have doubts about the quality)... Read More, and I don't exactly know how the holes started - if perhaps they caught a toe, or if there was a quality issue to begin with, or something else - but I'm only about five months in now, and the holes have since grown to the point that they need to be repaired or replaced. As the name suggests, the fabric is light and fits quite luxuriously in many ways, but the same quality that makes them so comfortable to wear also means they seem to be a bit too delicate/fragile for normal use.

Poor selection

Due to the very limited sizes available I chose the closest one, a large when I needed a medium. I thought if it was not wearable I could shrink it.

Comfortable and great fit

I am tall and slim - 6'3" and 30" waist. It is difficult to find clothing long enough that fits my waist.

I coach soccer and they keep me warm under my sweats and they are a great base layer for skiing and other winter sports. They keep their shape, also. Highly recommended!

Oversized thermals

I ordered large because the mediums were out of stock. I can normally wear large, but these were too long and too big around the waist. They took them back as a return with no problem.

super warm but loose fitting and long

The Capilene® Air Bottoms perform as expected, i.e, all that counts, really. But, a perfect fit for my 6' 1" 165 lb frame would be a slightly tighter fit from top of my thighs down to bottom of my ankles, and about two inches shorter. A medium might fit perfectly but not worth the exchange. I am happy enough with the long.

No fly opening in front!

It works

Midwestern climate is unusually cold this year. An extra layer that wicks well, is comfortable next to the skin, and does not hinder movement is just the right thing. The older I get the more I just like things that work. This does.

Best thing since sliced bread

I was hesitant at first. How warm could these be? Why are they so expensive? I decided to get them to try out believing that I would probably return them. How naive I was. They are fantastic.

Read More became something I wore any time it's cold out. They feel like you are wearing nothin' at all. They come around your socks and boots very nicely protecting your skin from snow exposure.

Much better than the mid-weight in my opinion.

After the first wash cycle (Cold & Gentle) it shrunk a tiny bit but started pilling SO bad, it looks like I've had it for 10 years, not just 2 weeks.

The lightweight Capilene bottoms of the very early nineties are still the best. Why was such a good thing abandoned?

When one layer doesn’t cut it...

This should do the trick in most circumstances. Not bulky, nor bunchy - just right

Would not recommend

Nice material but the material pilled up first wash

Whose brilliant idea was it

Whose brilliant idea was it to make this without a fly? The older bottoms have a fly! I have returned it. FWIW, I wish it were a bit longer in the legs (I'm 6'2).

awesome for cold days

I just went wade fishing on the Kenai River and it was cold. The air bottoms kept me really warm and they were super comfortable.

Love my gear, came on time and is in perfect condition.

Mens Cap Air Bottoms

Comfy, roomy, warm, true to size, i wouldn't call them slim fit, they kind of fit like the old expedition weight bottoms (2 gens ago), which is awesome. I use them as camp/sleeping bottoms so i like them a little bigger. That said, I would have bought a L instead of the XL. I bought the larger size b/c of my experiences in the last 2 years wit... Read Moreh your sizing. "Slim Fit" seems to be a little all over the map (maybe you all are playing with the range in size a bit?).

Soft warmth

The Air bottoms are nice and soft and warm and comfortable!

Comfortable Warmth

Super soft, warm and great fit. These are a looser fit than any other base layer that I have worn, which is my favorite thing about these pants. I use them mostly for work doing high rise/bosun chair window cleaning when the temperature dips. I do find them to hot for skiing or ice climbing. I pair it with the Capilene Air top and it is perfect!

Great product

I've had the tops for well over a year and just added the bottoms for the upcoming winter. Light, warm and comfy.

Not quite thermal pants, not quite long-underwear.

Love the material and fit of these bottoms. But the lack of a fly leaves me confused as to how I should categorize these. I bought a size larger (L) than I usually wear (M) so I can wear these over other capilene bottoms sort of like a thermal mid layer for super cold days.

Capilene Air Bottoms

Wish they had a fly! Other than that they are great. Run a bit large, mostly in the length.

Hi Nate! Thank you for bringing that to our attention. We are always looking for ways to better improve our products. In the meantime if you are for any reason unhappy with your Capilene Air Bottoms we would be more than happy to return or exchange them for a baselayer that has that feature. Check out our Men's Thermal Weight Bottoms that have fly access.

Great under wader pant for summer time

This is my first pair of these and Im definitely getting more. super breathable to let you stay cool when the sun is cookin, but provide enough warmth for endless hours of wading on northern BC rivers. A+

Really Warm Bottoms, Run Larger. NEED A FLY!

I got these with the top to wear as a set when snowboarding and climbing in cold weather situations. The bottoms run large, I would say I am a true to size medium for most bottoms. I wish I had a small for these. They are very warm and comfortable against the skin. I am not sure how Patagonia decided to not include a fly with these bottoms. A huge... Read More design flaw.

Capilene Air pants

Wore them fly fishing and slept in them at night during a camping trip on the Colorado River in Grand Canyon. Super warm and the fit is great. Worth every penny!

Love these

I can go from chopping wood to hiking to teaching my yoga class without an outfit change. Great fit and color. I have 3 pair and they are always my go to!

Great for under waders

Great fit, fabric and warmth. Pairs well with the RPS rock pants, and puff pants, as a base layer under waders.

February 27, 2019


Good fit a little room to move, warm and breathable. Don't mind the no fly like some others - with a pair of underpants underneath the fly doesn't seem that useful anyhow.

February 25, 2019


I have used these on ski trips 4 trips this year. I agree with other reviewers; why emasculate men's bottoms and not include a FLY? Albeit warm, hey are little too loose fitting for my liking especially when searching through layers to find a a FLY that's not there.... Seems more of a design for lounging than layering Maybe gen 2 will fi... Read Morex mystery of unrecoverable tackle.

Soft and comfortable

Warm, light, comfortable, you feel this pants like air layer :) Not tight, this is very good for long days in mountains. No fly? But no extra fabric and no uncomfortable points if you use Nano-Air pants (with stiff long zipper) with this layer.

Freeze when you have to go

Very nice and warm, it has legs long enough not to leave any gap around the socks. No fly might help keep you warm, but you will freeze when you have to go. If it had a fly it would be great. It would be nice to have the previous 1, 2, 3, or 4 on the label to make it easier to pick the right weight garment out of the drawer.

Very warm

Great pants, very soft and warm. They are a big long but fit as designed in the waist. Also the lack of a fly does not bother me at all. This product is a 5 out of 5 even if that is an issue for you these pants are worth taking that extra 10sec to unbutton pants.

No fly - No Buy

Title says it all. Fabric sounds enticing and I would be in but for the no fly zone.

September 20, 2018

No fly ain't fly

Love the material but the lack of a fly drives me (and a certain male part) nuts. Can't use them with a harness so the can't be used ice climbing, mountaineering, ski no, etc. Do any alpinists work at Patagonia anymore? Bad trend, bad decision.

The Return of Capilino!

The rebirth of the MerinoAir line is the best news: I wore my MerinoAirHoody daily for a month in the Alps - and nightly - and only got two or three chances to do something like a wash, and it turned out to be the perfect garment. Disappointed when the line went away, I ordered these the moment I found them (concealed by their new name). The new Ca... Read MoreplineMerino is softer than the first go around, appears to have transitioned away from what some 'men' felt was a feminine pattern (zigzags? really, guys?) and into the much more masculine waffle knit. I wore the hoody as a midlayer most days, and if it wasn't on me it was at the top of the pack. If anything, their sizing is slightly paranoid: I ordered the medium bottoms and they came in... too big, so I'm exchanging them for a small. Love this product, glad to see it back.
