Oakley has released its long awaited Carbon X® Complete Line of base layers! Oakley CarbonX Underwear is incredibly soft and lightweight while providing the new standard in fire safety gear. CarbonX® yarns and fabrics will not burn when exposed to intense heat or flame, because the actual fibers will carbonize and then expand, eliminating any oxygen content within the fabric. This gives it performance far superior to other fire retardant fabrics. CarbonX can provide critical extra protection when every second counts. Oakley CarbonX Underwear's soft knit construction is very comfortable and efficient in wicking moisture away from your skin.
