Full-coverage "boy shorts" built for sustained comfort under high-stress, high-activity conditions. Made with advanced fabric tech, but still amazingly lightweight, soft and comfortable. Patented non-melt, non-drip Advanced Protective FabricTM self extinguishes once removed from ignition source, giving armed force members added safety in the field. Fabric testing proves its X-Static technology is on par with Under Armour®'s Heat Gear for excellent moisture management during athletic activities. Plus you'll appreciate X-Static's odor-inhibiting properties.
