I have exercised in this t-shirt multiple times but it is time to pa** it on. You will love the ma**ive sweat and deodorant stains under the armpits and the strong sweat smell that's on it. I haven't washed it in a while and I just love to wear every now and then and go running and exercising, just to renew the smell. With a heatwave already hear and lasting for a few more days, this is gonna get some extra smell than usual.
