Snow camping, car camping, or hanging out in the cabin, these insulated puffy booties are irresistibly warm and comfy. Tundra Aerogel Booties feature a compression-resistant PrimaLoft® Aerogel insert that acts as a thermal barrier between your feet and the elements, as well as a weather resistant exterior shell and grippy print on the sole. Insulated with VerticalX™ ECO, these offer a superior warmth-to-weight ratio that works even when wet. An ankle cinch top will secure these around your calf for all-day or all-evening warmth.
