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. (This review was collected as part of a promotion.)

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.

Rated 5 out of 5 by from This product is perfect for outdoor activists I work outdoors and found this product perfect for keeping body heat in without bulk. It's also cute when going indoors for breaks. It fits snug but moves with you. I'm normally medium and medium fits perfect

Rated 3 out of 5 by from Snug arms I wore this baselayer skiing in VT last weekend and liked the performance fit except for the upper arms, which seemed too tight though not enough to really bother me.
Date published: 2016-02-13
Rated 5 out of 5 by from wonderful under garment. Warm and comfortable. It can be worn by itself. The omni heat is great.

Rated 3 out of 5 by from Love omni heats! While the pants seem to run large on me, this top seems to run small. The arms are particularly tight. After examining the 2 pieces, I realize that the top is a waffle weave fabric with little stretch, while the pants are smooth with lots of stretch. I wish the top was the same as the pants.

Rated 5 out of 5 by from thermal undergarment This product runs small, but it sure did the job in keeping me warm under my outer shirt. The fit is just the way I like an undergarment to function. It's long enough to tuck into my pants and does not ride up. The sleeves are the perfect length also.

Rated 4 out of 5 by from This top runs a little small The body of the top fits fairly well, if a little snug (and I do have a larger chest), but oddly, the arms are noticeably tight. It's not bad enough that I cannot wear it, but I am ordering another one in an XL.

Rated 5 out of 5 by from a must have Fits snugly, but I guess it's meant to actually be that way to seal heat in. Has been keeping me warm in -20 ish weather underneath a rather flimsy parka. A must have for sure!
Date published: 2016-01-14
Rated 4 out of 5 by from Runs small I'm normally a size 6 and I could barely get the shirt over my chest. It was too constricting to wear for any length of time. With the omni-heat inside, there is no give to the fabric.
