I've got an entire capilene 2 set-up to include long-sleeve top, bottom, and boxer briefs. Having bought other baselayers, I always end up wearing these. They're softer, less restrictive, and more comfortable than say, UnderArmor, but performs just as well.

This is the good way to stay dry and cool despite harsh climates. This knit is open for a little breathability and wicking performance yet insulative enough for active use on cooler days.

Best of the Best, Didn't take a shower for 9 days while in the woods and it still didn't stink...Kept me cool and warm

Like it! Have two Capilene 2 T-shirts that I have in large as I like mt T-shirts loose. This one I bought in medium so its a little more fitted to layer underneath other stuff. Although the sleaves could be a little longer (most climbers I know have a pretty good ape index...), its warm and I rate it.

This may be a wonderful product for wicking moisture and keeping me warm backcountry skiing, but it's got a few major seams on each arm and a few on each side of the shirt. The material is so fine that the seams are pretty huge, and they itch. I just wouldn't want this rubbing on my skin all day.

While not cheap...it does as advertised. Softer and more comfortable than most wool based products, it provides great warmth and wears well. Any outdoor activity done in cold weather will be much more enjoyable with this acting as a buffer between the skin and the weather. I bought three and they get plenty of use. Thumbs up!!!

As a base layer, it adds some warmth and can be used for casual wear as well. By itself, it would be comfortable to wear even in hot weather- the open knit mesh type construction allows you to feel the breeze on your skin. Super light weight, and seems kind of delicate but I have had no problems yet.

I purchased the Capilene 2 Crew Long Sleeve for an everyday base layer. Perfect for keeping you warm and comfortable throughout the day. Vents well to keep material smelling clean, go weeks without washing.

Looks and fits fine. Works as it's supposed to and is just as good as fancier shirts that cost twice as much. The blue is even a nice color. And.. Patagonia is a good, socially responsible company. Am happy with my purchase.

I will admit this is my first good quality base layer... I can think back to soccer when I was sporting some Champion brand spandex but I did pick up the full Capilene 2 system and am amazed. Comfy, slightly loose fitting, breathable and very quick drying all as advertised. My only gripe is with the durability, I am a little worried as I have had these for about one month and gotten quite a bit of use from them already, the shirt has been flawless while the pants have a small rip starting in my inner thigh. The only thing I have used them for thus far is biking and the rip would make sense if there was anything sharp around my saddle (which I made sure there is not). It appears the rip might be coming from repetitive stretching? I have yet to contact Patagonia yet to see what they have to say. But worn as a base layer this stuff is amazing!!! just watch out for snaggs and maybe stretching the fabric to much. Thanks!!

The perfect baselayer for 15-40 deg weather. Add a vest and some sort of windblocker or shell and I am toasty. Good wicking properties, good heat retention and decent antimicrobial, although if smells are your big issue, then maybe the patagucci wool is your bag.

This is a great product.

this is my new favorite shirt...it keeps you dry and it's versatile enough to wear all year long.

This is a great underlayment! It does not shed sweat, but it keeps you extremely warm!
