The Black Pearl Bike short is made from tricot knit fabric that is highly aerodynamic and hydrodynamic. The microfiber nylon is 87% micro-denier Nylon and 13% Spandex. It is beefy weight and offers supreme compression for enhanced blood flow. The compression supports muscles and movement. This reduces muscle fatigue and lactic acid buildup. This blend of nylon fibers allows for a very soft feel that dries instantly and “sweats well” during your workout. The slick surface reduces wind drag and promotes aerodynamics for speed and energy efficiency. The Black Pearl Crotch pad will be the most comfortable pad you have ever worn! It is made of long lasting Poron for anti-shock and comfort. This shock absorbing cellular urethane is designed to absorb shock for the life of the short. It is breathable in that it lets water vapor and perspiration move away from the body. This pad resists abrasion, is smooth and wrinkle free. The black pearl will not change its properties with usage and will not harden or soften with use. The Poron cells are “open cell structure” which allow water transportation while maintaining its ability to absorb shock without bottoming out.
