Original Mountain Marathon (OMM) Core Sleep Sock OC175, Color: Gray/Navy

These fleece socks are made with PRIMALOFT ACTIVE, a revolutionary padding material. With a minimal pack size and weight, they can be stored compactly until bedtime. They are designed to enhance the warmth of the extremities even with a lightweight sleep system. They are not intended for commuting.

PRIMALOFT ACTIVE: We've blurred the line between fill and fabric, using Primaloft's industry-leading synthetic fill fibers loosely woven into a fine polyester mesh. The result is warmer than traditional fleece at less than half the weight. It performs like down when dry and retains its warmth even when wet.

It is intended for use in tents or sleep systems only, and is not recommended for use in active environments due to durability concerns.
