Rated 5 out of 5 by from Great baselayer shirt I normally wear a size small. I own three colors of this shirt in medium and it fits me perfectly. Order a size up. I love this shirt. When I downhill ski, I wear this shirt, Columbia’s Omni heat vest and my ski coat and I am perfectly comfortable. Anything more than that and I end up removing layers and carrying them in my backpack. It breathes great. I’ve also worn this hiking and it’s fantastic. The only negative to this is that the material is “cold” when you first put it on. Once you warm up, it stays a very comfortable warm level.

I discovered this long sleeve t shirt when we We’re at the Christmas markets in Europe! I had been wanting to try one but did not want To pay full price but I did!!!! It worked great so when I got home and saw they we’re on sale I bought a lot more! I found them a little tight in the arms but not bad. I wears small i’m 5’1 Not binding! Will buy more. They wash well

Rated 5 out of 5 by from Love It! This is my second one. I bought this shirt two years ago for a trip to Antarctica and decided I needed another one. I'm always cold. This shirt keeps you toasty warm but breathes. It is form fitting. If it wasn't, I'm sure it would not be as warm.

Rated 4 out of 5 by from Amazing Baselayer First thing, these run small! I'm glad I went with an XL instead of my regular L. But this kept me warm while hiking along the coast when the winds picked up. I wore with the half zip for sleep when the temps hit the high 30s and was warm & comfortable. Definitely would purchase more.

Rated 5 out of 5 by from Love it! I love this baselayer. Third one I have purchased. I first one I purchased was Medium and it fit but didn't have much stretch. The second one I ordered was large and it fit much better. The third one order is a large also. Love that I don't have to pile on clothes for me to be warm. If more colors come out I will definitely be ordering more.

Rated 5 out of 5 by from Warm and breathable I fell in love with Colombia's Omni Heat technology in the leggings. Needed a baselayer for a winter photography expedition in Iceland. First time for me to use a shirt in this material; as an older woman, hot flashes are an issue. Tested it out in -20C wind chill this week. Wore it under a light sweater, with a down coat. Walked about 1.5 km, then went inside in full gear. It was GREAT! It's breathable, so it didn't make me break a sweat but it also kept me nice 'n' cosy in that cold. Super comfortable, too. I ordered XL because I am muscular, but short; fits me like a L, which is exactly what I wanted, so perhaps it fits a little small. (This review was collected as part of a promotion.)
