Capilene® Polyester Baselayer

Made from moisture-wicking polyester, Capilene® synthetic baselayers wick moisture away from your skin, breathe efficiently and dry fast to provide the foundation for any layering system for any pursuit. Designed for fast-forward, aerobic activities, they’re quick to wick and quick to dry. Capilene polyester is made from recycled polyester (30% recycled content or more) and is also machine washable.

We make four Capilene fabrics for different levels of exertion and temperatures. All Capilene fabrics have achieved bluesign® approval; have an updated and consistent fit in each fabric weight; and use Polygiene® technology to control odor in the garment. They are the best baselayer option for high-sweat activities and wet conditions.

Men's Capilene® Lightweight Bottoms is rated 3.7 out of 5 by 13.
Rated 5 out of 5 by from Great base layer I have both the top and bottom lightweight layer and it's perfect as a base layer during mild days and even during hotter temps. I mostly use them as a nice layer in between my more uncomfortable uniform items and myself. It also really helps to manage sweat if I'm required to wear long sleeves and pants at work during hotter days.

Rated 5 out of 5 by from They are long underwear Its just long underwear. Nothing fancy. They keep my legs warm and dry skiing. The last pair I bought lasted six years of wearing them 5 days a week, so I definitely got my money worth.

Rated 5 out of 5 by from Light and airy! As an outdoor educator, I spend a lot of nights in the field. I bought this layer principally for my sleep system. Each night before crawling into my sleeping bag, I put these bottoms on to reduce the build-up of "sleeping bag funk" (e.g. sunscreen, sweat, oil, etc.). They are very light and extremely breathable.

Rated 4 out of 5 by from Very much improved from previous designs I recently bought and wore these lightweight bottoms under waterproof pants for hiking in temperatures ranging from 45-60F in a very randomly rainy environment (the UK). They did everything they are supposed to do, which I suppose is high praise. I don't think you'll find a better baselayer (But I will mention below why this doesn't get 5 stars). I can tell you honestly that if you're working hard, there's no need to buy even midweight unless it is so cold you probably shouldn't be hiking. Regarding size, take into account your leg muscularity/girth--I am 5'10", but the large fit best because thigh/calf width causes the fabric to stretch horizontally and therefore naturally shorten vertically. In summary, someone my height with a slight build might need a medium. There is just one thing that keeps this review from being five stars, and it's a problem with basically all baselayers on the market: the crotch area is too long (you can see this in the picture). When they are pulled up to your waist, there's still a big open space down there. That open space acts like an oven, and you keep having to jack them up when that becomes a big, sweaty problem. Now, concerning Patagonia, this issue has improved. It was even more of a problem with these bottoms when I bought my first pair 15 years ago--the old ones I would give three stars.

Rated 5 out of 5 by from Perfect for me As others have mentioned, these do run smaller than your typical size. I'm 6' 205 lbs and the Medium fits perfectly - waistband is comfortable, legs are not too tight or baggy. For anyone interested, these weigh 3.5 oz. Not sure about durability as I just got these but wanted to get this review out there mainly for the fit/weight.

Rated 5 out of 5 by from Best ever I use this article as pajama bottoms and it is unbeatable. This is the second pair I have used in this manner.

Rated 3 out of 5 by from Usual high Capilene quality but runs large These seem larger than usual - unexpectedly baggy for a medium. Consider going down a size if you are a typical medium build.
