Rated 5 out of 5 by from Warmth and Freedom Columbia's Omni Heat is the first fabric I look for when it comes to wanting to be comfortable outdoors in frigid weather. This shirt has been indispensable this winter. It's my go-to base layer for hiking and cycling in sub-zero weather and it never lets me down. The quality is outstanding and, even after daily use and frequent laundering, it looks and feels brand new, ready to hit the trails again! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from great product I purchased multiple base-layers including lightweight, mediumweight and, heavyweight and I love all of them. This is easily one of the most functional products in my closet. I wear it as a base layer when skiing, under a light jacket when hiking and just on it's own during chillier spring/fall mornings. It always provides enough warmth and keeps incredibly dry regardless of the activity.

Rated 5 out of 5 by from Very Warm I had a friend recommend the medium warmth baselayer, so I decided to buy the heavyweight since I get cold so easy during winter activities. Wearing it in the house, as I got ready, I started sweating. It is definitely warm! The last waterfowl hunt of the season was very cold and incredibly windy. I know I would have been much colder without it!

Rated 5 out of 5 by from Warm, Light Weight The shirt runs small. The shirts are made out of a different material than the pants and are not as stretchy. I usually wear a medium but got a large in this top. It fits perfect in the shoulders and arms but a little big around the waist (I usually wear a medium so I figured it would be this way)

Rated 4 out of 5 by from Decent and warm It works well under cold weather.

Rated 5 out of 5 by from Amazing heat retention Kept me warm and dry. Got to test it out in Utah on Powder Mountain. It was snowing all day as we snowboarded in the powder. I wore this and a puffy coat and then my winter coat. Didn't really need the puffy. It is snug but that's really what you want. It is long enough to tuck in your pants or long underwear. It didn't ride up or anything which was really nice.
