Sleek and supportive, the Nike Men's Hypercool Comp 3. 0 6in Short optimizes compression and moisture wicking comfort during high octane training sessions and competitive use. Dri Fit fabric facilitates the evaporation of built up perspiration to reduce the clammy, sweat soaked feel during intense exercise. Mesh Dri Fit side panels enhance ventilation when you're running hard and training at the gym. Additionally, the elastic waistband keeps them nice and secure during rapid movement, while the flatlock seams ensure a smooth, non irritating fit underneath your running shorts or exercise apparel.
