For years, Patagonia’s Capilene Bottoms have been a core piece of outdoor gear for both the extreme adventurers and weekend warriors alike. For 2010, Patagonia improved Capilene’s ability to stretch (without adding spandex), made the waistband more comfortable, and reinforced critical seams for added durability.

  • Capilene baselayers trap warmth next to your body and wick water vapor away from your skin, which helps you maintain a consistently comfortable body temperature over time
  • Capilene is stretchy, breathable, and provides an excellent warmth-to-weight ratio
  • Patagonia’s Capilene baselayers come in four weights (thickness): 1 is silkweight, 2 is lightweight, 3 is midweight, and 4 is expedition weight
  • Capiline 2 is the stretchiest and most breathable of Patagonia’s baselayers for your high-aerobic pursuits
  • Slim fit for that warm, next-to-skin feel
  • Patagonia assumes you like to work hard and get dirty—fabric contains Gladiator odor control to help tame your garment’s stank
  • Patagonia makes its garments with environmentally sensitive practices, and, once you’ve thoroughly thrashed your bottoms, you can recycle the bottoms through Patagonia’s Common Threads Recycling Program

Here's what others have to say...



    Functional but I prefer the feel of merino or other fabrics to capilene.


    Great, one gripe.

      Wick like no other synthetic fabric. No itch. No irritation. Regulate body temp very well. Pair with a Cap2 top, its a perfect baselayer.

      They stretched out after using them for half a backpacking season and a ski season. Waist band is looser and the crotch is sagging. Do I still wear them? Yesh. Would I buy again? Yuppers.


      Excellent for winter.

        These are super warm,yet amazingly light. Paired with a soft shell pant, as long as I'm moving, I'll be comfortable into the 10� realm. They are extremely thin, almost sheer. When wearing them however, you barely notice them due to the comfort of the material.


        All you need

        • Gender:Male
        • Familiarity:I've used it once or twice and have initial impressions

        These are all you really need as a cold weather hiking base layer. Put these on under my hiking pants before hitting the tent on a 38 degree night and I was plenty warm. Great deal and service by BC.


        Still my favorite.

        • Gender:Male
        • Familiarity:I've put it through the wringer

        Merino's nice and all, and I enjoy merino baselayers, but these are still my favorite long undies. I find the no stink benefits of wool to be more significant in a top than in a bottom, and merino is so delicate I've torn merino bottoms just putting them on.

        I've used Cap 2 bottoms forever and think I'm done looking for a replacement. I can chill in them in cold weather without freezing my little buns off and I can run around in them without heating up my nether regions to the point of nuclear fusion.


        Great base layer

        • Gender:Female
        • Familiarity:I've used it once or twice and have initial impressions

        Got these for my boyfriend, and he loves them. I also bought the women's version for me - they are perfect. Lightweight, but keeps you warm.

        how do I choose my size s/m/l/xl? I normally go by waist inches.

        do you ship to Australia?

        There's a sizing chart for you, just above, below where you choose your size and color.


        lightweight and warm

          Just these and my shell pants and I was never cold. Lightweight and comfortable. Pretty much standard stuff...


          love 'em!

            These are amazing. I have never had a baselayer, and never thought I'd like them. But I splurged and bought these and i am glad I did. They do not bunch up when I'm on the mountain all day and they don't compress to the point of blood loss- which was my main concern because I have giant legs- I'm 5'11" and 180#s I bought the Medium and I love them. I wouldn't want any other size.

            I paired these with the Stoic Bombshell Bibs and was absolutely warm enough to ride all day in 20 degree temps. (I'm stay warm easily, though)

            Bottom line: Keep your boys from freezing off with these.


            Flexile base layer

              Works well for most cold aerobic activities, alpine skiing, etc. I prefer a thin layer under a shell, but I run pretty warm, so you may want to try the Cap 3 midweights if you run cold. Fabric is nice to the touch, itch free. Waistband is comfortable and doesn't dig or anything odd. Washes up really well and doesn't seem to hold odors. Super excellent base layer!


              The Best Around

                I don't know if I can say anything about these layers that hasn't already been said, but these are the BEST baselayers created. Really Patagonia's capeline entirely is fantastic, but I use the 2 the most because of it's versatility. They breath like a champ, wick sweat rapidly, are thermally efficient, and are tremendously light and comfortable. They are indispensable in my skiing and fall backpacking wardrobes and they are the only layers I bring out on trail. The waist band is really comfortable and none of the seams chafe, my only concern is no cuff on the bottom of the legs.


                Good product.

                  These are relatively light weight but seem to do their job well. The crotch area is a little long. I would rather have an inch or so less material between the crotch and waistband.


                  Best I've found

                    My husband wants a second pair of these. They're durable, versatile, comfortable, and warm. He wears them under shells for snowboarding and during the summer when camping at altitude.


                    Surprisingly warm

                      Holding these in your hands, these don't have a lot of heft. It's amazing how warm they are -- either under a pair of jeans on a workday, or under Powder Bowl Insulated pants for skiing. These are versatile, they are well-constructed, and they don't bind, pinch, or itch. Very nice.



                        These are one of two options I'll pull out for ski season. The other being running tights by Under Armor. These are alright, nothing super special.


                        Best baselayer available

                          Sure you can pay a lot more for merino, but these hold up great. They are lightweight and super soft, and are either warm or cool depending on how you need them to be. They wick great, and dry super fast. I wore the bottoms after it got a little cold for just my Marmot softshell pants and they did the trick. They are skinny around the ankles too, so great for not being bulky around your boot/sock line.


                          I Love This Base Layer!

                            I have multiple pairs of the Cap 2's and I wear them all winter and they feel great and keep me warm! I will definitely keep buying that Cap 2 Base layers!


                            They got this one right

                              I love my pair. Great for cold nights or cold hikes. Breathe great, and avoids odors nicely, which is great for longer trips.


                              great insulator

                                these things work great as an insulating piece. i slap on these things when i know it's going to be a cold day (between 32 and 0 farenheit) and couldn't be happier. my only complaint would be that the elastic around the ankles seems kind of big. usually have to pull them back down into place several times throughout the day. but, that's not a big deal.
