The SPRAWL Performance Tees are designed for moisture management, comfort and durability. The polyester micro-venting system allows sweat to pass to the outer portion of the garment so it can evaporate keeping the athlete cooler and dryer than traditional tee shirts. Light stretch properties provide a comfortable fit and freedom of movement. These Performance Tees were designed to be versatile enough to wear for grappling, sparring, under gis, running and all manner of cross training. Their understated design also makes them viable as casual wear in hot weather conditions.
