The crew-height Slate Mountain hits at mid-calf for fully cushioned protection while wearing mid-height boots. Outer nylon plaiting construction delivers a traditional look that positions merino wool fibers next to your skin for maximum wicking and insulating power as well as natural odor resistance. Sourced and made entirely in the US, the Slate Mountain will stand up to years of rugged use in true backcountry environments.
U.S. Merino Wool
Merino wool is soft, itch-free, naturally odor- and bacteria-resistant, cool in the summer and warm in winter. We source our 100% U.S. grown merino wool exclusively from sheep raised by American farmers on American farms.
Outer Nylon Plaiting
A more traditional sock construction technique that produces classic linear patterns and heather textures, outer nylon plaiting knits the stretch yarns in the outer layers of the sock and the body yarn on the inside. Reinforcing yarns woven into the stretch shell increase durability, while wool fibers sit closer to the skin for maximum insulation.
Top-to-Toe Cushion Zone
Top-to-Toe cushioning increases comfort in heavy, high-volume footwear like hiking and winter boots. Cushioning loop knit along the instep and up the shaft of the sock adds insulation while protecting the foot from stiff boot tongues and uppers.
Full-density cushioning features a terry knit loop on every interior stitch, providing better insulation, exceptional wicking, and increased protection against impact. Its faster moisture absorption keeps the skin dry and reduces friction, while its shock-absorbing nature enhances the performance of multi-sport and outdoor socks.
Seamless Toe Closure
Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction.
Circumferential compression from the top of the sock through the arch creates a precise, comfortable fit that helps support the foot throughout the day.
Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock.
