Extra thin and pure performance, the new Sno Comp uses patented Dri-Stride® technology to keep your feet warmer and drier in even the most extreme weather, without any added bulk. How is that possible? With the magic of the patented Dri-Stride® system: separate and unique zones absorb then transfer moisture up and out of the sock. The first step to staying warm is staying dry and this sock is a pro! The beautiful winter tree design for women and the performance mesh for men enhance the rate and quantity of evaporation, creating super highways that speed the moisture removal process. For maximum comfort and light weight performance, this sock is very thin and without any cushion.
