I got annoyed with paying 50 to 100 bucks for a workout shirt, so I was thrilled when I found Grunt Style T-shirts. The company's run by veterans and they make an inexpensive, great looking, great fitting T-shirt that comes in a bunch of colors. Best of all, their lifetime "Beer Guarantee." You tear it, spill beer on it, or get "blood stains from defending the American flag from terrorists," they replace it. – TC Luoma
