These down booties are perfect for keeping your feet warm during winter activities like hiking, skiing, or camping, as well as for staying cozy indoors. Filled with 90% high-quality down, they provide excellent insulation and relief for cold feet. The ultralight design (only 40 g) and compact storage bag (9 x 15 x 5 cm / 3.5 x 5.9 x 1.9 in) make them easy to carry anywhere. Available in sizes S (27 cm), M (29 cm), and L (31 cm), they are ideal for temperatures between 0 and -15 (32 to 5 ).The hydrophobic fabric on the surface and bottom resists water and ensures breathability, while the 700FP fill power enhances warmth. The soft, skin-friendly material can be worn barefoot or over regular socks for additional insulation. An adjustable drawstring on the upper part allows for a snug fit, preventing heat loss and ensuring the booties stay securely in place while walking.
