Played with a guy Monday who was wearing a UA Heat Gear shirt. I usually wear Walter Hagen shirts. With the heat cranking up to 100 degrees + now, the Hagen shirts I wear aren't so cool, sweat a lot. He mentioned how cool his UA shirt was and I noticed no sweat through staining his shirt. Went to GG and checked out their UA shirts and bought one. Played yesterday and that shirt is GREAT. Feel like you're not wearing a shirt at all and no sweat through either. You get what you pay for and I will buy more of the UA Heat Gear shirts.
