PhD Outdoor Mountaineer Sock Men's

The right gear can make or break any expedition. The Smartwool PhD Outdoor Mountaineer sock is their most technical mountaineering socks ever. They put some serious sock science to work in these all mountain socks, including revolutionary Indestructawool technology for ultimate durability and the 4 Degree elite fit system for a dialed fit. With high density cushioning where you need it most, in the heel and toe, all while using a flat knit on the leg to accommodate low volume mountaineering boots. Mesh zones offer breathability, flex zones offer added comfort, and Merino helps keep feet warm, dry and comfortable.
