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.
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.
Thanks for your feedback, Charlie. We're very sorry you don't like the design on the Capilene Air Bottoms. You're welcome to [return](https://www.patagonia.com/returns.html) them at your earliest convenience if you aren't satisfied.
Too bulky for very active winter outdoor activities.
I play outdoor hockey in Minnesota. The temperature is always below freezing and typically below zero. You're freezing your butt off when starting but are sweating profusely after 20 minutes of hard skating. These bottoms do not wick sweat very well. They seem to act more like cotton thermals than capilene. They are really comfy when starting ... Read Morethe activity but are too bulky and uncomfortable after the activity starts. The old lightweight capilene was perfect. It provided a great baselayer and effective wicking but was not bulky and uncomfortable. Please bring those back. I have dozens of Patagonia products and found nearly all of them to be excellent, except for these air bottoms.
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...

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.
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.

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.

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.

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!
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.
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. 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...

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.
Warm and Dry
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.

Warm, not durable.
Works as described. Very comfortable against skin and warm. Not the warmest I have ever used but comfortable while active. My biggest issue seems to be with durability.

Decent, but a step back
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.

Thanks for your feedback on the Capilene Air fabric, Ryan!

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.
On in October and they’ll come off in April!
Well, I do take them off for occasional laundering, but seriously, these are the softest, most comfortable long underwear I’ve ever had. Wildly light as a feather too. And warm, warm, warm, though always just the right warm; I never find them hot. Like merino’s but better. These are unquestionably the best long johns I’ve ever had. I can’t wait to ...

I usually always do buy size largess; not sure why I didn’t here... But I can see where a less loose large pair would be more snug on the leg which could well look after the statically excited problem. Cheers and warmth from the Yukon!
Comfy but wears down fast
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.

Amazing fabric.. Longevity, not so much.

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.

Too long to be useful
If you look at the video, the model is six feet tall and wearing a size medium and the material is all bunched up at his ankles.

Simply trying these air bottoms on, the amount of material bunched at my ankles is a deal breaker. waist fits fine, material is excellent, stretch is excellent. When I ordered these, I watched the video and ordered the small to cover all bases, yet as I suspected the waist of the small is too tight. How do we go from small is too small and "medium" is too big. out of curiosity I measured the inseam on my patagonia expedition weight bottoms and they are 27 inches while the new air bottoms are 32 inches long. It could also be that the expedition weight (older style) have a panel crotch vs the air bottoms which don't. My patagonia midweight bottoms are closer to 27.5 inch inseam and again with a panel crotch and also fit great.
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.
These long john bottoms do not come with a sewn in fly. Seriously? My bad, upon more careful inspection of the picture it does not show a fly, so I'm just passing along what I found out the hard way.

NOT a warm top layer for sedentary people
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.

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.

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.
