Rated 4 out of 5 by Birthday gift I have a shirt very similar to this one. I bought this for my boyfriend as he works outside a lot. I like the material used for the shirt. The shirt is very very small, I knew the shirt would be smaller than size so I bought a 2X largest size sold when my boyfriend wears a X-Large. It fits him rather snugly... especially in the chest. I would recommend sizing up more than one size unless you will wear a shirt over it. I wish it had more of a neckline to cover to protect your neck from sunburn. September 19, 2013
Rated 5 out of 5 by Amazing shirt for the heat! I wore the Coolest Cool long-sleeved shirt during a 100-mile race where temps got up to the high 80s and it was absolutely amazing! I never had an issue with the heat. I could immediately feel a coolness when I put on the shirt. It was unbelievable. It will definitely be my go-to shirt during hot races in the future.

Rated 3 out of 5 by Omni Freeze Zero Performance I'm a fan of Colombia products and continue to be. My review of the Omni Freeze Zero Performance long sleeve shirt revolves around two elements. It's SMALL. I'm an XL and have lost some weight over the past year, almost a large. This product in XL was extremely tight. Maybe it needs to be to maximize moisture wicking. Love the Colombia quality, the style, color, etc., but bottom line is that I see NO difference between this new product and any recently produced moisture wicking product. They all work well and I just don't see any material difference. August 18, 2013
Rated 5 out of 5 by took to Maui for Snorkling Not only great for Snorkling but hiking and overall wear. It is comfortable, cool and dries fast. July 22, 2013
Rated 5 out of 5 by Comfortable and Cool This is a comfortable shirt that will indeed keep you cool whenever there is some air movement. July 22, 2013
Rated 5 out of 5 by Stays cool in hot humid conditions plus more I was skeptical but had to try a short sleeve version in my spin classes where it really helped an uncomfortable environment. So, I used the long sleeve on a 250 mile summer bike ride and I'm very happy to report I am completely satisfied. No sun burn, great comfort, and no bad smells. I did wash the shirt out each night and learned the best thing to do was to put it on wet and enjoy a much more comfortable evening. Next time, I'll take only one shirt and save some weight.

Rated 5 out of 5 by Coolest Cool Works The Long Sleeve Coolest Cool shirt really works. When temps rise this is the shirt you need. The hotter it gets the shirt actually cools your body. the first shirt worked so well I will be ordering several more. July 6, 2013
Rated 4 out of 5 by Not bad I had a 50% off cupon it was worth the buy but not so much if I had to pay full priced. Fit tight good kept cool if I was sweating protected from the sun. I suspect it would work really well in humid environments I was in the mountains in co so had good sun protection. July 5, 2013
Rated 1 out of 5 by This product doesn't do what it say It doesn't cool. Wicks moisture away, but no cooling affect whatsoever. A whole lot of money for a shirt that only wicks moisture. Very disappointed. June 28, 2013
Rated 5 out of 5 by great shirt I work in Tampa, Florida with a lawn crew. It is summer here now and I needed a long sleeve shirt that could replace sun screen and cool me off at the same time. This fit the bill and I researched every shirt that competes with it. I am very glad I made this purchase. I have had it for 2 weeks now and I have been testing it to the brutal max! First of all, I will say it feels a tad weird at first when you START sweating, kind of like waring what I would imagine to feel like seal skin. but it keeps all the poison oak and lawn debris off me, it defiantly holds its promise to be SPF 50. In fact it works tad too well...I have a pasty white torso and native American hands and face. As for the cooling, It works but not well if its very humid like where I live it gets to 90% and sweat can't evaporate! But when the sun is beating down on you and a slight breeze hits, it feels like an ice sheet is on you because of this shirt. All and all, I feel it is WELL worth the cash if you are in my type of sun and heat exposure, if I was just doing my own front yard for a few hours, I would just put some sun lotion on. Last, it fits just like Under Armor, although, I ware a Large in UA and with this shirt a Medium fits perfectly with room around my wrists. June 25, 2013
Rated 5 out of 5 by another great one for hot climes! incredible product for super hot weather June 24, 2013
Rated 4 out of 5 by It does keep you a little cooler! It is a nice shirt, although expensive. I use it for bicycling in the tropics. I notice when I get it wet by pouring water on it, it works very well at cooling. For sun protection I wish the collar came up higher to protect your neck. The SPF Factor works perfect. After 4 hours no sun burn. Sleeves are good and long. It runs slightly small in size. I am 6' 177 pounds, thin shoulders. I would order XL next time. My Wife likes hers also. June 22, 2013
Rated 4 out of 5 by Does what it says I just wore this shirt fishing on a 91 deg. day in the sun and I couldn't feel the sun through the shirt at all. I didn't feel hot either like I do in just a T Shirt. A Breeze really makes it feel cooler than in a T Shirt. I found that the size chart is real close to the actual size of the shirt. Early in the mornings when it is a little chilly around 55 deg. I didn't get a chill it was just the opposite it was warm enough that I didn't have to wear a light jacket. June 15, 2013
Rated 5 out of 5 by Just Short of Wearing a Fridge I am 6'2" ~180lbs and ordered this in a large. This is a nice stretchy body hugging baselayer. The vivid blue and white does a nice job of not absorbing the sun's heat when worn alone. Compared to Omni-Freeze and Omni-Wick Evap this concept of sweat control puts them to shame. Omni-Freeze Zero is a perfect step towards controlling that nasty clamy sweaty sticky fried feeling I get when I am outdoors for hours in the sun. So far I have used this shirt for prolonged hikes, hours on end of paddling up and down rivers, fishing, and as a moisture control baselayer. The one thing that sold me on this technology is that the omni-freeze zero does not start cooling until it is damp. This feature is vital at keeping you at the exact temperature you need to be at, especially for the cool mornings when you are starting the day's hike or enduring the cold winds on a kayak in the middle of lake. Taking into account Columbia's unique fitting style, products like these win me over every time. Thanks again Columbia May 17, 2013
Rated 5 out of 5 by cool I have not used mine yet but had it demonstrated to me. I was amazed on how it works. Most of the time people make clams and when you try it, at best you think ya I can see that. But this was wow how does that work like that? Try it !! May 12, 2013
Rated 4 out of 5 by Nothing special Although it did keep me dry and protected from sun rays, i never felt any cool effect as advertised. It s not cheap but i hink allmthis 'freeze' thing is just a gimmick! May 1, 2013
Rated 5 out of 5 by Great Cycling Baselayer I use this as a baselayer for cycling. In 75 degree weather it was just perfect. Kept me cool and makes as a great sunscreen. March 30, 2013
