Outdoor Research Men's Tundra Slip-on Aerogel Booties Prussian Blue

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 adventure into a luxurious experience without the extra weight. These ultralight indulgences will make the biggest difference on your snow camping, mountaineering, and backcountry hut trips. 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. VerticalX™ insulation offers a superior warmth-to-weight ratio that works even when wet, and the grippy soles are perfect for walking on slippery snow and ice. A collapsible heel can be worn up, or tucked away to convert booties into slippers.
