Men’s Baselayer Midweight Mock Neck Long Sleeve is rated 4.3 out of 5 by 17.
Rated 3 out of 5 by from A little chilly... Great fit, but not warm at all. Bought this for use in outdoor cold weather, 28F to 45F and high wind open ocean sail racing conditions. Been wearing it around PDX to see how it works before going offshore. The metal-like foil flakes feel icy at times, even indoors. It's a very snug spandex-type fit, but the sizes are true. It would work as an intermediate layer with a full sleeve layer underneath, but it is not as good as similar Columbia products without the foil flakes.

Rated 4 out of 5 by from Keep active This base layer works if you keep moving. If your just sitting in the elements, it's not very effective. When exercising, it does a good job. The dots stick to the skin but only noticeable at first.

Rated 5 out of 5 by from Comfortable and warm Top was comfortable and warm. Perfect for layering under other garments for moderately cold skiing conditions. This was a perfect find for the trip to Colorado for snowboarding.

Rated 5 out of 5 by from Omniheat Midweight Base Layer I purchased the omniheat midweight base layer for my son to wear under a uniform shirt at Les Schwab tires. He loves the snug, flexible fit and it serves to keep him warm on chilly days. He's asked for a second one!

Rated 5 out of 5 by from Winter Hike,Winter Warmth wearing this baselayer ! Went on a snow shoe hike on a new trail in the heart of the Adirondacks,NY. Temp in morning start was 10 degrees and warmed to 20's by end of hike. Wind whipping on summit = COLD ! Omniwick and omniheat performed well. While hiking up sweating i vented and shirt performed top level while keeping me toasty. Great midweight baselayer with added omniheat makes this a must have to all winter hikers !

Rated 5 out of 5 by from Warm in New England I bought this baselayer shirt for my husband as a Christmas gift. He works outdoors. Today was 8 degrees. He told me that baselayer that he's worn in the past keeps you at a consistent temperature, but this baselayer actually keeps you warm! So happy I bought it!

Rated 5 out of 5 by from Liked it so much I ordered another. This top is lightweight, fits well, feels good, and keeps me warm. I wear it under a long sleeve shirt in the winter.

Rated 5 out of 5 by from Does what it says I wore this outside with a thin cotton shirt over it. I got cold with a cold breeze. It almost amplified the wind. However, since this is a base layer as the name implies, it does what it is supposed to when layered with windproof material. It kept me warm while outside when I was dressed in layers. I was definitely very warm when wearing this with the same cotton shirt indoors, even when I was not active.

Rated 4 out of 5 by from 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.

Rated 3 out of 5 by from Very warm! The baselayer is very warm. Just know that it runs small! The Details state that there are "thumb holes", but they are not on the product that I received...kinda disappointed.
