Nice Item These are very warm when outside in cool weather, and of the very good quality one can expect from Columbia. I feel they run a little small, but they are not tight or confining. I like things to fit a bit looser, but as a base layer maybe this is how they should be. I ordered a large after reading other reviews, and am glad I did. I wear a 15.5/34 dress shirt, and a large is 'form-fitting' on me. November 19, 2012
Keeps it warm I haven't really tried on a long outdoor activities yet it seems keeps the heat well behind this base layer. This Omini-Heat technology does work. My skink felt more warmer than standard base layer that only uses Omini-Wick. I'm quite impress with products. I got this from the outlet online here in Columbia. October 5, 2012
Baselayer Great shirt. The stand out comment I would make is that it is long in the body. If it comes untucked from your ski pants you had quite a tumble! September 12, 2012
Great way to say warm with a light weight shirt Men's Baselayer mid weight short sleeve top - with Omni - Heat. This shirt does keep you warm with out the bulk of other warm clothing. Size is listed as XL when it is more like large. September 6, 2012
Totally Awesome! I had to exchange a Large for an X-Large (I wanted a little more room) and finally got to wear it it last weekend for ice fishing and snow camping. Wow! It's a great shirt, I'm totally happy, it's worth every penny. I crawled in my sleeping bag with it on, but had to take it off, at 32 degrees, it wasn't cold encough to wear it at night. Thanks for another great product. January 31, 2012
Very Good So Far I live in FL, and believe it or not, it does get cool/cold here at times. I have worn this Baselayer just a couple of times and I only needed a windbreaker over top and it kept me very comfortable. I do travel up north during the holidays and occasionally for work, when required, so I just ordered the heavyweight long sleeve top and pants Baselayer just to be prepared for the really cold weather.

Great Product! fit, form and functionality as one always expects from Columbia! November 18, 2011
Light and Warm I wear it almost daily. It does make a difference in staying warm.Very soft like a t-shirt. I had tried on a size large at the store, in which i normally wear. It was a bit to restraining. went to a size larger, fits great. Well made. Light and warm. November 14, 2011
