Avoid moisture, friction and blisters with the Drymax Hyper Thin Running socks. Designed to be the world's lightest running sock, the Hyper Thin sock is about as thin as a dime. Built with a race proven Dual-Layer Sweat Removal System. Because moisture does not adhere to Drymax fibers, they mechanically lift sweat off the skin like a squeegee and transfer it to the sock's outer layer. This system works so well, Drymax guarantees it will keep feet dry and comfortable in all types of footwear in all conditions.
