The body sweats to cool you down. Underarmour is supposed to be very tight fitting and retains the sweat inside the shirt. I've got an underarmour shirt, it's the heat gear. That's the cheapest for tight fit and it's $25. With my associate discount I got it for $20. Turf gear and cold gear can run clear up to $35-$40. I work at a sports store by the way, and I was ringing up this lady that basically got a TON of underarmour. She had maybe 15-20 underarmour items, and she spent well over $300!
