Columbia Omni-Freeze Zero

Columbia Omni-Freeze Zero
A technical fabric for hot weather activities. Hike or run the day away with a fabric that drops the temperature of the material, all with the power of your own sweat. Not only does the fabric feel cooler, but it dries fast too, so you remain comfortable.

A moisture-wicking fabric for active pursuits in warm weather. It works to pull moisture away from the skin, then evaporates fast, so you remain dry for the rest of the adventure. It works just as hard as you do.

Rated 5 out of 5 by from Form and function The innovative Vent-Air mesh fabric is super light, quick drying, and has a bit of stretch for flexibility. I like the long sleeves for some protection from the sun, as well as flexibility for dynamic weather conditions. At first I wasn’t crazy about the hidden security-pocket as the zipper made the shirt bulge oddly when tucked in, but I found that simply unzipping the pocket largely alleviated the issue. The only improvement for this shirt would be the button-down, sun-protection collar (like the Lo Drag shirt). I’m 5’5”, 120 pounds and got my usual Columbia size small and the fit was great. Expensive, but good addition to my summer wardrobe. Overall, I love this shirt and hope more colors will be available soon.

Rated 5 out of 5 by from Keeps you cool and dry! [This review was collected as part of a promotion.] I love these shirts! I have 3 with short sleeves and 2 with long sleeves. They are great for hiking on warm or hot days, and nice-looking for casual wear or travel. Long sleeves are almost as cool as the short sleeves, and protect from mosquitoes! Please make more color choices and offer them in short sleeves again! Also please offer them in long sleeves for men, and more short-sleeve color choices for men!

Rated 5 out of 5 by from Cool, Comfortable and Classy I love this shirt so much that I have bought it in all three colors! I love how light weight it is and easy to pack. It's also versatile in that you can wear it with sleeves up on a hot down or down when it is cooler. It's a nice enough shirt to wear on more dressy occasions. Overall, a very high quality, comfortable, cool, sporty, yet classy shirt!!

Rated 5 out of 5 by from Loved this shirt [This review was collected as part of a promotion.] I bought this top to go fishing in the sun and I loved it. It fit great, was lightweight, and protected me from the sun while keeping me cool. I love the fact the sleeves can roll up, but since I was in full sun I never used that feature. I bought this in two colors since I was so happy with it.

Rated 5 out of 5 by from Why are there not more colors??? Just received this shirt on Aug. 15, just as the Pacific NW was settling into Day 1 of a major heatwave of triple digit temps (very rare for us!). I was wearing a lightweight denim sleeveless shirt when the package arrived, and was surprised when I tried it on at how much cooler this fabric seemed even though it had sleeves. I ended up wearing it all day! I’m short and a little busty (36D), and the XL was perfect (I don’t like clingy fabrics when it’s hot, unless it’s a swimsuit or my bike kit!). The nocturnal Heather color is prettier in person than on the website. I was so happy with it that I went to see what other colors it came in, and only saw a drab gray that wouldn’t do me any favors. Hoping for more color options like black, white, and perhaps a subtle print.

Rated 5 out of 5 by from I love this shirt This shirt has the most interesting fabric. It's so lightweight and if you hold it up, it's sheer, but when you put it on, it's totally opaque. It's beautiful. And cooling! I love, love Omni Freeze. I have spent way too much money on Omni Freeze clothes, but they actually work. I get really overheated when hiking, and I'm so much cooler in them. I wish the logos weren't so prominent on the clothes. I usually don't buy clothes with logos on them, but Omni Freeze works, so I have no choice.

Rated 5 out of 5 by from A Staple for an Ultrarunner [This review was collected as part of a promotion.] Wow! I bought the shirt for a purpose, and it sure does deliver. I am a distance runner who needs sun protection for the long haul. Reapplying SPF every hour is a lot to think about during 8-10 hours on the trails. This DOES keep cool and very is breathable. I bought a small. I’m 5’6” and muscular. It is tight in the shoulders and arms, so if you lift weights even just to keep tone, know that it might be snug.

Rated 5 out of 5 by from Awesome Shirt! I initially bought a petro blue heather shirt and loved it so much that I purchased a cirrus grey heather one as well. I love this shirt. It works great for hiking and general travel. Keeps you cool while still looking good. The only thing that would make this shirt even better is for Columbia to remove the side zipper pocket as it sometimes rubs a bit if the shirt is tucked in. Would love if the shirt came in more colors.
