Utilising innovative NASA-approved insulation, lightweight and compressible the Tundra Aerogel Socks offer a protective, wind-resistant, toasty warm place for your feet after a long day of cold weather adventuring.
The exterior of the sock is wind- and water-resistant polyester and it extends well up the leg to provide excellent coverage. The booties are filled with PrimaLoft Gold synthetic insulation with Cross Core Technology. This high-performance insulation incorporates fibres embedded with Aerogel to provide exceptional heat retention and moisture management even in damp or wet conditions. An interior tricot liner provides next-to-skin comfort.
Other features include an ankle cinch that prevents snow or debris from getting into the booties and anti-slip polyester microsuede soles to keep you stable.
