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.
Thank you for the thoughtful feedback on sizing, fit, fabric and comfort of these Capilene Air Bottoms. We're sorry to hear about the lack of durability. Please know that the product is absolutely covered by our Ironclad Guarantee, so don't hesitate to reach out about returning them.

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. The waist fits but it is four or five inches too long. Now I have pants only a skinny giant will be able to wear.
I was originally looking for your Capiline silk weight pants and boxers. Where can I f... Read Moreind what I am looking for?
Hey Tony, thanks for leaving us a review on our Capilene Air Bottoms. Any time you're wondering when an size or color is going to be restocked, feel free to reach out to us as we're able to check inventory for that. It looks like the size medium for these will be coming back in July. If you'd like to begin a return for the size large, please get started [here](https://www.patagonia.com/returns.html). Unfortunately, we no longer carry the silk weight line but we're happy to pass the word along that you'd like to see that come back.

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. This would fit someone with a larger waist, as there is ample stretch in the waist, but they are long enough for me and slim enough that they don't fall down. Very soft, they breath great, and they keep me warm but they aren... Read More't "hot" or uncomfortable. 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!
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.
Hey there! Sorry that's a deal breaker for you and please feel free to [send](https://www.patagonia.com/returns.html) this back to us.

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.
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.
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. I wear them all the time during these cold Chicago winters. Originally I needed them as a layer while I waded around in the freezing Chicago river. But these... 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. They do not ride up or create friction. But they do add a nice layer of warmth. Even in -10 degree F weather, these things feel fine. If you are looking for a base layer go for these. Much better than the mid-weight in my opinion.
Would love to wear these for all my cold-weather activities, but recently experienced the no-fly issue while wearing a harness -- not fun or easy. The fit is perfect for my larger thighs and calves, though this is likely an issue for thinner folks. I usually am an XL in all this patagonia, but went with a Large. I'm typically soaked through wi... Read Moreth sweat after fatbiking and these are the only piece on me that stay warm and dry through the ride. I expect some issues with longevity as well, partly because I wear them almost exclusively and partly because they seem a bit fragile.
The capilene air fabric is solid, but not great. I still find myself reaching for my old beat up capilene silkweight base layer. That fabric was much softer and seemed to be a tighter weave. These aren't in the same class. I don't understand why they changed their fabric to a lesser result. While the capilene air is comfortable compared t... Read Moreo some products, when compared to the old silkweight it feels scratchy. It doesn't stand out. The competitors products are at least as nice.
Thanks for your feedback on the Capilene Air fabric, Ryan! While the Silkweight Capilene has been discontinued for quite some time, the Capilene Air is intended to be a warmer layer while still being breathable and more comparable to our Thermal Weight Capilene.

Just right warmth
I'm outside every day for a long walk, or bike ride, and at my age, warm legs are important. These Cap-air bottoms are great and the perfect base layer under Torrentshell pants.
I have a Capilene Aire Hoody that has a slim fit in size medium that is just perfect! Bough the bottoms to round out my classic cross country ski base layer kit. The bottoms are warm and somewhat comfortable. The fit is a bit loose and length a bit long for inseam. This is in comparison to other Patagonia bottoms. Small size would be too small. I g... Read Moreave it 4 star and love Capilene Aire
I love the breathability and stretch of the fabric, but they are pilling badly in the crotch area after just a few wearings and washing. The fabric there is noticeably thinning. They will not hold up through a ski season. I am also disappointed that the men's version doesn't have a fly.
Hello William, we're sorry to hear these baselayer bottoms aren't holding up after only one ski season. Please feel free to [return](https://www.patagonia.com/returns.html) them to be evaluated under warranty.

Warm and comfortable to wear
Fits well and I have rather large calves and thighs--no problem at all. I've worn them running and under pants, and in both cases I was very comfortable in below-freezing temperatures.
Only downside so far is care instructions are only in German and a few other languages, but not English.
These would be great if they had a fly!! Most men dont sit down to pee so Im not sure how these were designed without a fly? Its just common sense to put a fly on them especially for the price they are they should have a fly.

Breathable, weak structure, poor design, and poor build quality
First off, I want to love these. I really do. However, I don't. The fit is loose, which, like many reviews have stated, will make it much harder to trap heat. The material is soft, and gentle, nice to have up against your body on long days. But, the stitching/knitting/composition of the material is horrendous. The threading on the fabric is to...

Makes me feel warm all over.
Great for living in Fairbanks Alaska. Any and all uses from lounging to working outside at -30.
I was super excited to wear these cause they are incredibly comfortable. At first they we well worth the steep price. But they pilled fast and I just noticed two holes in the crotch after only about 12 wearings. I maybe washed them once. Im disappointed cause I wanted them to last. They are also a little long and yeah, theres no fly.
Hi Dan, sorry to hear about your experience with the Patagonia Men's Capilene® Air Bottoms. We stress our clothes every time we wear them, so some degree of pilling will happen. Here are some steps you can take to keep your knitted gear in rotation longer. Give your Capilene® Air Bottoms a wash every 2-3 wears, then tumble dry at low temperature, or dry flat. Sweater stones are also good way to gently remove pills between wears.
If you feel that your gear has not met your expectations, please feel free to begin a warranty return under our Ironclad Guarantee, https://www.patagonia.com/returns.html.

Great texture, too long.
I love these thermals. The waffle-ish texture really traps warmth and theyre mad comfy.
I will complain that theyre just too long. Im a normal size. 61 & 190 lbs. and the Large size fits great. The only problem is that the legs are all the way down on my feet.

Overall, love them. Just a feature to be aware of
Very warm, fits well even under slim fit jeans, and basically unnoticeable against the skin. That being said, on the model the material looks painted-on-tight, but these are actually a bit baggy.

Used at home for two weeks.. didn't get the chance to test it outdoors... I own a Capilene air hoody, and I really like it.
I bought this, initially, to use as base layer for a thru-hike. I thought I'd try it out at home for a while before taking it on the trail, just to find out how much would it stretch and shrink between wash cycles.
... Read MoreOut of the box, it looks and feels amazing, but a little loose, not as "slim fit" as I thought. I could pinch about an inch "and some" of extra fabric at my thighs.
After about three days, it had stretched out so much that it looked ridiculous under my shorts. 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. Even with all the pilling (all over) and some fraying (at the crotch), it is still soft and warm, but unfortunately I don't think this piece will be used for anything beside sleeping, at home.
I would buy this again, if the pilling issue can be fixed.
Hi Hussain, we're sorry to hear about your experience with the Men's Capilene® Air Bottoms. Knit garments will inevitably pill due to the nature of the fabric. These pills can be removed will a sweater stone or fabric shaver. Not only will they help to remove the little fabric nubbins, it will also lengthen the life of your Patagonia gear. You can learn about removing pills at wornwear.com. If you feel that Capilene® Air Bottoms haven't performed to our standards, please feel free to begin a warranty return under our Ironclad Guarantee, https://www.patagonia.com/returns.html.

Awesome Wool Blend Baselayer
This review will be very similar to the Capilene Air Crew. Wearing both the top and the bottom at the same time grants a Morrowind-esque feeling of set-bonus attributes: plus 10 to warmth when worn together. The bottoms are good with undies; they're also great without. The lack of a fly is bonus to me; keeps the draft out and prevents accident... Read Moreal presentation during "baselayer-only" parties.

But where they really work well is when just sitting in the winter on the boat for hours just steering the boat. (Your just sitting there not creating heat). With this set up, you stay nice and warm. Being on the water in mid winter is brutal, but these make it almost a comfortable experience (almost, lol)
They have stood up to daily use for the last 6 months. I know they are a little pricey, but Patagonia did a great job with these. Was a great investment for me and I know Patagonia stuff will last for years.

Long johns
Great, but I got a size too big. I got large, but should have gotten medium. I’m 5’10”
I’ve been wearing Air tops for a year, in all kinds of conditions. Ultra light weight, breathes well, and warm. These bottoms fit and feel great as well.
Love all my long underwear from Patagonia, these are particularly warm. I would say they run a little bigger than the other pairs I've had, so I got a LG instead of XL, and they're perfect.
After opening them and trying them on, I didnt take them off for 4 straight days because how comfortable they are. Great for everyday wear under lighter outdoor pants in the colder months, not too hot with a lighter pair of pants, not too warm. Can’t say anything bad about them.
I'm not an outdoors person; I'm someone who sits at a computer in an old, cold house. I've used Capilene Expedition Weight tops and bottoms to keep me warm for years.
I decided to try Capilene Air to see if it's even warmer. It's not if you're sedentary, and it's the top layer. The "breathability" means... Read More that drafts go right through the fabric.
I expect Capilene Air would fare much better if you put on a wind-stopping layer over it, and if you're active. But it's not a good base layer for sitting around in.
Great Capilene bottoms but they could be better. A wider variation of sizes would help make me feel like you actually cared about ME. Not Maine, me. One size does not fit all. nor does three or four. We are not all the same height. I am a trim person at 5’9” yet the medium waist is too tight, the length too long, and the volume too voluminous. On t... Read Morehe positive side, the soft comfort and the cozy warmth are wonderful. And finally, it’s early November, barely the start of the cold season in the Northern hemisphere and yet Patagonia is totally out of medium navy colored men’s Capilene Air bottoms. Big let down. The lightweight Capilene bottoms of the very early nineties are still the best. Why was such a good thing abandoned?
Hi Adam, thanks for taking the time to write us a review! We're really sorry to hear that the bottoms pilled after the first wash. Your satisfaction is always guaranteed so you're welcome to [return](https://www.patagonia.com/returns.html#searchterm=return).

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.
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?).
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!
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.
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+
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.
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!
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!
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.
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

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.
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.
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.
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 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.
