Utilizing innovative compression-resistant NASA-approved insulation, the lightweight and packable Outdoor Research Tundra Aerogel Socks keep your feet cozy warm after a long day of cold weather adventuring.
The exterior polyester shell is wind- and water-resistant, and a high cuff extends above the ankle for excellent coverage. The socks are filled with PrimaLoft Gold synthetic insulation with Cross Core Technology. This high-performance insulation incorporates fibers embedded with Aerogel to provide exceptional heat retention and moisture management even in damp or wet conditions. The Aerogel material also retains its insulating properties even when compressed underfoot. An interior tricot liner provides next-to-skin comfort.
Other features include an ankle cinch that seals out cold drafts and anti-slip polyester microsuede soles to keep you stable if you need to move around camp.
Sold in pairs, the Outdoor Research Tundra Aerogel Socks are available in your choice of sizes and colors.
