Under Armour Base 1.0 Crew Top - Mens 2009

Pull on the Under Armour Men's fitted Base 1.0 Crew Long Underwear Top for early spring runs. Under Armour's thermal grid fabric looks sort-of like a computer keyboard the grid-channel troughs trap air and cut down on the amount of yarn, so the Base 1.0 feels light, wicks, and dries quickly. This long-sleeve top also neutralizes odor-causing microbes, so you won't smell like a sweaty horse after your training run.
