Hotter than the blazes down here in Northwest Florida. Anybody using the UnderArmor sports t-shirts as a work shirt? They wick perspiration away from the body. Supposed to keep you cooler. I also umpire and they work great under the umpires uniform shirt. If anyone does use them, have you had them screenprinted with company logo? Can you screenprint them? I've been wondering about them for awhile now.
