COOLMAX® Extreme is a performance fabric that is perfect for physical fitness and other high exertion activities. This proprietary polyester fiber has a unique engineered microchannel cross section that can move perspiration away from the body much faster than natural round cotton fibers. Getting perspiration to the surface of the fabric keeps you cooler and dryer and thus more comfortable. Besides its positive effect on maintaining body core temperature, Coolmax® resists fading, shrinking and wrinkling.

  • 100% Coolmax Extreme Polyester
  • Made in the USA


COLOR: Black, Brown, Sage or Sand

  1. Mediocre Performance 3 Star Review

    Posted by

    I bought three of these in olive green. I live in florida year round. I wore these shirts during the month of december and I found out the following about them. Pros: well made using dupont coolmax fabric, nice color, easy care washing. Comfortable made in usa cons:the fabric feels comfortable but warm on you're skin without noticeable ventilation. The knit is tightly woven.Not much different than a regular tee. I did a direct comparison with a british army coolmax shirt and the british army shirt was the clear winner. A good all around tee shirt for workouts and general purpose but I wont buy this brand again.

  2. Amazing Shirt 5 Star Review

    I knew this would be a great shirt right out of the box! I wore it the next day on a long run and it was dry in minutes. I will definitely be getting more of these in different colors for variety! Thanks us cav for yet another amazing product!

  3. As Promised 5 Star Review

    Posted by

    I said in may that I would give a review after I tested the shirt through the summer. After a few trips to go shooting outdoors in this incredibly hot summer in socal, I will suggest that everyone get at least one of these shirts. So far no fading, stretching or anything bad. I bought one in every color. The shirts kept me cool and dry incredibly fast. I took a trip with my children to legoland, they have a water park area. After getting soaked head to toe my shirt was 100 percent dry in 20 minutes, while my shorts were wet for hours. These shirts feel soft when you wear them and keep you cool and dry while everyone in cotton shirts have that nice sweat patch on them for hours. I loaned one to a buddy on a hot day and haven't gotten it back. He is certain that I had treated the shirt with something to make breathe and to stay dry. I would love to take credit for it but it's just the shirt! Get one and tell me i'm wrong. It would be even better if they had them in white or even a selection of colors with a tight v neck collar.

  4. Best Leo Undershirt Ever. 5 Star Review

    Posted by

    I'm a uniformed officer in san bernardino, california. The temperture in the summer hovers around 90-105. This is the only shirt i've ever used that dries nearly instanatly the moment I take my vest off. These shirts are nearly as soft as cotton, but don't absorb sweat like a cotton shirt. The collars stay tight, and I have yet to notice the black shirts fade. All in all it's the best undershirt i've worn. Honestly, these shirts outperform shirts costing two and three times as much. They won't keep you any cooler, but they will keep you infinitely more comfortable. The only downside is that being polyester I don't believe they are fire resistant. I don't think these would be a good choice for outside the wire, but they would be ideal in any other situation.

  5. Worth Every Penny 5 Star Review

    I just received two of these shirts in xxl (black, od green). I am 6 foot 4 240 lbs and the size fits me perfect. I love the feel of these shirts and they do stay pretty cool. I will be buying a couple more of them. They are made of 100prct dupont coolmax polyester material. I will test these out in the desert in the next few months and will report my experience.

  6. Great Shirt, Price Is Right 5 Star Review

    Posted by

    I've owned a few of these shirts and just ordered 3 more. They're a very good choice if you're budget is not unlimited and you need more than one. Wicks well, dries fast, stays clean. It also stays together well if damaged. I managed to catch the bottom of the short sleeve in some equipment and it bit about 1 square inch off, right on the seam. I washed and wore it again several times without unraveling. Worth the $10 or so every day all day.

  7. Great Work And Activity Shirt! 5 Star Review

    Posted by

    Bought 5 of these brown shirts when I was in the army and know wear them in a hot, humid warehouse environment. These shirts keep my body cool and dry of sweat! I would recommend these shirts for anyone who doesn't want to spend big bucks on under armor and want something that isn't imported! Great for outdoor or heavy duty work, and even casual wear, truly flexible.

  8. Very Comfortable 5 Star Review

    I have about 3 of these in the sage green color and they're very nice for working out, running or wearing under your uniform. I'm thinking about getting some in the tan color. I would definitely recommend this product to a friend.
