Here's what other sites are saying:
Train harder, play longer and recover faster. The men's 2XU Compression 3/4 tights enhance training, performance and recovery. Graduated compression reduces muscle fatigue, enhances blood flow and offers excellent support to help reduce muscle damage. Specialized, circular knit ensures even pressure around the circumference of limb. 50-denier LYCRA(R) spandex delivers strong compression, fabric protects skin from harmful UV light with a UPF rating of 50+. Antimicrobial treatment helps reduce odors. Flat waistband with internal drawcord personalizes fit. Flatlock seams reduce chafing. If near the borderline for sizing, and if you wish to wear your compression garment primarily for recovery, choose the smaller size of the men's 2XU Compression 3/4 tights.
