the OMM Core Tent Sock – Ultralight thermal socks for tents & sleeping systems

The OMM Core Tent Sock is an ultra-lightweight, packable fleece sock designed specifically for use in tents and sleeping systems in cold conditions. Featuring revolutionary PRIMALOFT® ACTIVE insulation, it delivers impressive warmth-to-weight ratio – perfect for mountaineering, fastpacking and expeditions where every gram counts.

The insulation blurs the line between traditional fleece and synthetic padding. Primaloft® ACTIVE loosely weaves insulation fibers through a fine mesh, providing down-like warmth when dry and reliable insulation even when damp . The result is significantly warmer than fleece – at less than half the weight.

The socks are designed for rest and sleep only , not for active use. The minimal seam construction reduces chafing and keeps weight down, while the PointZero nylon ripstop sole provides increased moisture resistance. A silicone logo on the sole provides better grip on tent floors and sleeping pads.
