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 shorts.  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 the ability to absorb shock without bottoming out.
