Our Active Chamois utilizes a 4 ways stretch seamless antimicrobial compound for frictionless biomechanics. A gender specific design utilizes air channels for increased air flow and faster dry times, while a multilayer tier system reduces pressure in delicate areas. High quality, high comfort training. Full comfort that fits snugly through the knee for extra cover and lower leg support. The soft shaped 2 inches comfort waist keeps from feeling too tight in riding position, even with the compression style.
