Fans of Nike know that Nike Pro helps them stay focused during their workouts by keeping them comfortable. The brand mark first appeared in 2005 on athletic base layer apparel, and the evolved selection now spans fleeces, jackets, tops, pants, tights and shorts for men and women. It’s made for thorough training conditions and matched by thorough testing, such as dragging barbells across a pair of tights or rubbing the fabric against a gym floor to simulate abrasion.
