Cold Weather System Socks Two socks work better! Lorpen's Cold Weather System socks include both an outer sock and an inner liner for ultimate warmth. The inner Merino Wool sock helps wick away moisture. Warmth is then trapped between the inner sock and the outer Italian Wool sock making for excellent warmth and comfort.

Lycra® Adaptability This fiber has the best zero-point elasticity and is the only fiber that conserves its characteristics forever. Lorpen socks are the only technical socks that include Lycra® throughout their entire structure. No creases, no abrasion, no blisters.

Extra Flat Toe Seam Our toecap mesh joins each stitch up with its partner on the other side without creating a traditional seam line or those bothersome ridges that can hurt your toes.
