Women's Coolest Cool™ Long Sleeve Top is rated 4.3 out of 5 by 19.
Rated 5 out of 5 by from Perfect fit for runner who needs sun protection As mentioned on the website, it fits a bit snug, but thats how I like to wear my running clothes. Since I am usually a medium, I went for the medium and I love the way it fits. It's perfect for me for running in Mexico City where I need to be protected from the sun especially on warm days. This shirt has high UPF protection and it very breathable so I don't get too hot while running.

Rated 2 out of 5 by from This product was disappointing I thought the shirt was white, instead it had small blue dots all over. I should have looked at the more detailed view. I would have sent it back but I would have to pay for the shipping. Still contemplating whether to return it or not.

Rated 5 out of 5 by from Great Sun Protection As a dedicated football fan, I needed protection from the sun. This product not only provides that protection, it also offers Omni-Freeze Zero which wicks perspiration away and aids in cooling you. After trying the shirt & experiencing it's effectiveness, I purchased another one. (Some weekends both our NCAA & NFL teams have home games!) I highly recommend this product and shared the information about it with my dermatologists. Now they are suggesting it to other patients.

Rated 4 out of 5 by from Makes hot weather bearable Wore this shirt on one of the hottest days when I had to walk my dog. It kept me comfortable. My only complaint is that it ran a bit small in size which made me want to wear a larger shirt over it. However, when I tried that it undermined the purpose of the shirt.

Rated 5 out of 5 by from Great product! I am wearing this shirt as I write this review. I live in Florida and work in elementary physical education. It's very hot and humid here and I was looking for an alternative to sticky sunscreen that needs to be reapplied. I was skeptical about the cooling affects and was worried about being too hot, but I have to admit I'm impressed! I am comfortable and used a misting bottle that enhances the cooling effects. I ordered my usual size and the fit was perfect. Fitted, but not skin tight. For reference I am 5'2, 108 lbs, 32b and I ordered the xs. I highly recommend this product. My only regret is that I didn't order other colors before they ran out of my size!

Rated 4 out of 5 by from Not as good as the reviews I purchased this shirt based on others' reviews. I brought the medium because everyone said that they ran small but it's a bit too large, long in the sleeves. It's gotten pretty wet with sweat and while it wasn't uncomfortable, it didn't provide the cooling action the reviews and description said it would. I'll try it a few more times but I'm not sure that I'd get more of this line. I wish I had gone with the small but there are no stores around here that carries it and I didn't want to go through the hassle of returning it and find the small really is too small. It's not true to size for sure.

Rated 5 out of 5 by from Protects you from the sun while keeping you cool. Hiking leaves you exposed to the element of the sun but with the Omni-Freeze Zero long sleeve shirt protects you from the UV rays and yet keeps you cool through it's patented wicking fabric.

Rated 5 out of 5 by from Great product I run 6x a week and have a variety of high tech shirts - and as we all know - they are not all equal. This is a great shirt - and I got the full sleeved small - and I wear a size 4 - and this top works really well. It's super lightweight on - it doesn't move. I have tight/compression like tops that move up my abdomen - this doesn't. And it soaks up the sweat w/out the fabric getting heavy w/ sweat. It stays light. Great trick there Columbia. I did a duathlon w/ it over the weekend - the top was a breathable second skin and SPF to boot. And it looked great after the event too - am considering buying a second one.

Rated 1 out of 5 by from No black I don't know why you would make a black shirt for anyone who needs protection from the sun. Even with the so-called "cooling" ability - if the wind is not blowing, the black is hotter in the sun than other colors. Also - fit runs VERY small - and I ordered a size larger than I normally wear. It was still skin tight - and, as an older woman - I do not wear skin tight clothes. I ordered the men's shirt in a larger size, and while it is almost a dress on me, and the sleeves cover my hands, at least it's not skin tight.
