NASA-approved insulation, adventurer-ready slip-on bootie design.
Throwing a pair of the low-ankle Tundra Slip-on Aerogel Booties into your pack turns any snow camping, mountaineering, or backcountry hut trips into a luxurious experience without the extra weight. Each bootie features 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. VerticalX™ ECO insulation offers a superior warmth-to-weight ratio that works even when wet. A collapsible heel can be worn up, or tucked away to convert booties into slippers.
