Rated 4.5 out of 5 by 17 reviewers.
Rated 5 out of 5 by Warm long sleeve baselayer. This garment helped me thru the cold days of the last week. I'd buy another one if the cold was going to be around longer. December 23, 2016
Rated 5 out of 5 by Happy enough that I've ordered two! Not only am I very happy with the product I was very happy with the service and the speed in which I received the product!! Thank you December 21, 2016
Rated 5 out of 5 by Great 1/4 Zip This is a great shirt and the material is beyond compare. I am 215lbs with a athletic build and the XL runs a little to tight for my liking (but it is designed to be a base layer). I wear this short a lot and have found it to be very tough and well crafted (like most things Columbia!!). That is the reason for 5 stars despite that it runs small. I can always buy a larger size If you plan to wear this over a T-shirt or another base layer then I would size up at least one, maybe two sizes. October 26, 2016
Rated 5 out of 5 by very nice I like it very much. This is my main running top now;) July 10, 2016
Rated 5 out of 5 by Great Shirt I bought this shirt for a base layer in the cold mountain hikes. I have been out in 32 degree snowy weather and it functions as says. It kept me a tad hot but did an excellent job of wicking sweat away. Great base layer shirt for anyone out in cold weather. June 4, 2016
Rated 4 out of 5 by Great Base Layer! This product worked great. fit was a bit tight but not so much as to squeeze you. very light and thin fabric surprised how it kept me so warm! February 25, 2016
Rated 5 out of 5 by Great Base Layer Nice product with good warmth. Even has a zipper guard. February 22, 2016
Rated 5 out of 5 by Warm and functional Combined with mid weight base layer no issue with keeping me warm when fly fishing, snow shoeing or kayaking in cold weather. Simply a great base layer combo and like all other Omni Heat products, you stay warm. February 22, 2016
Rated 5 out of 5 by Nice Comfortable. I'd seen mention that this shirt tended to be smaller than the label size, so I bought an XL instead of the Large I would have otherwise ordered. I was not disappointed. I'm tall and the XL fits me well plus it gives me a little more sleeve length. Plus, this shirt comes with thumb holes in the cuffs - pretty much guaranteeing that the sleeves will be longer than usual. This shirt seems a bit thin for what I would have considered mid-weight, but I'm no expert. I have the heavy-weight version of this shirt on order now. February 18, 2016
Rated 4 out of 5 by Omni-heat is great! This products features work very well! Fits smaller than usual! January 25, 2016
Rated 3 out of 5 by not like the "original" I have 2 of these, white and black, that I bought 2 years ago and absolutely love them. this new blue one is no where near the quality or the fabric weight... all 3 are "medium weight" but this new blue one is way thinner! January 20, 2016
Rated 5 out of 5 by Good Fit Bought this for outdoor activities in the cold. so far I am pleased with the performance of this baselayer. like the half zip for cooling off when temp rises. will definitely purchase again. January 16, 2016
Rated 4 out of 5 by Space age The top runs a little small. I'm 6'1" 270lbs. would have gotten a 3xl if they had one. I can feel it heating me up. The little mirrors inside the top reflect your own heat back into your body. Very space age. December 31, 2015
Rated 5 out of 5 by Next Level in Base Layering I wore a moisture wicking t-shirt with this over it, and a Columbia Omni-heat parka skiing in about 15-20 degrees. I was cooking! So plan on one less layer than you're used to. Fits tightly, not too small, more like a compression shirt. Great midweight layer! December 15, 2015
Rated 1 out of 5 by poor fit so small it was useless, no thermal properties, and restricted movement. November 29, 2015
Rated 5 out of 5 by Great for Motorcyclists We motorcyclists buy a lot of very expensive gear to enable ourselves to ride year round. Well, the Columbia baselayer gear eliminates that nonsense. Some guys ride around looking like the Michelin Man or wearing their summer gear but freezing. This stuff is the answer. Now I'm sure other people have known this for years but this is my first time wearing baselayers. When I start out in the morning and it's 45 degrees out but later the temp rises to 85 degrees, I'm not that uncomfortable. That's hard to quantify and very hard to put a price on. Good stuff. November 21, 2015
Rated 5 out of 5 by So Warm. This is an excellent base layer that allows full function and keeps me warm. November 2, 2015
