Outdoor Research Tundra Aerogel Womens Sock Insulated Bootie Footwear

​The Tundra Booties from Outdoor Research feature PrimaLoft® Aerogel Insulation; the lighter, thinner, stronger insulation trusted by NASA space travel. Whether you are snow camping, car camping, or just hanging out in the cabin, these insulated booties are like a warm hug for your feet. 

The compression-resistant PrimaLoft®​ Aerogel insert acts as a thermal barrier between your feet and the elements, as well as weather resistant exterior shell and grippy print on the sole. Insulated with the 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. 

Put your feet up after a long day with these irresistibly warm and comfy booties!​
