Key Men's Enhanced Visibility Long Sleeve Pocket T-Shirt 838 39

These shirts actually do ventilate and live up the manufactures claims. I've tried Walls, Jockey, and several others, only to have them be very hot and only slightly better than Cotton when it comes to keeping you dry and moving the moisture away from the skin. Also, a real bonus is the price. These are even cheaper than the Walls brand short sleeve at Walmart. Use a laundry soap that is made for this type of tech material. Ordinary laundry soap with it's whiteners and fabric softeners will clog the pores of the material and then it won't breath and they can get really hot. The cheapest one that works can be bought at Walmart in the sporting goods department. It's called Sport Wash and it doesn't cost any more than any good laundry detergent. The only complaint for this shirt is quality control. The pockets are not very square. They are sewn on slightly tilted on some of them and somewhat off to the side. Not a lot and not a big deal but that's why only 4 stars. Oh, and these are really bright too!
