Flash Down Booties

Flash Down Booties – Ultralight Down Booties for Backpacking and Cold Camps The Flash Down Booties are the gold standard in ultralight down booties for backpacking and cold weather camping. Weighing just 3 oz (85g) per pair in size medium, they deliver exceptional warmth, comfort, and compressibility — all in a package light enough to blow away if you leave them out on a windy day. Whether you’re warming up after a long day on the trail or relaxing at an alpine basecamp, keeping your feet warm plays a critical role in regulating your overall body temperature. The Flash Booties feature 850+ fill power ethically sourced goose down, offering reliable insulation even when the temperature drops. The shell is built from 12D ripstop nylon that’s ultralight yet durable, allowing the down to loft to its full potential. A 1/4″ foam insole adds lightweight underfoot insulation and support, while the simple elastic drawcord closure seals in warmth just above the ankle — no frills, no unnecessary weight. These booties are designed for serious outdoor use, but they’re equally at home in a mountain hut, backcountry yurt, or your own living room. Ideal for anyone with cold feet or poor circulation, they provide packable comfort that goes wherever you go. Highly compressible and warm enough for deep winter trips, the Flash Booties have become a must-have for ultralight backpackers, thru-hikers, and mountaineers alike. When every ounce matters, and warm feet mean better sleep and better mornings, the Flash Booties are the gear you’ll never leave behind. Made in USA. Click here for bootie size chart.
