The Naturehike Y150 Ultralight Cotton Sleeping Bag is built for adventurers who refuse to compromise on warmth or packability. Rated for temperatures between 0°C and -10°C, this 3-season bag handles spring, summer, and autumn conditions with ease — whether you're pitching a tent in the mountains or relaxing at a base camp. Its 190T polyester outer shell and 190T Pongee lining wrap a generous cotton fill that retains heat without adding bulk. At just 1.3 kg and packing down to a compact 22 × 43 cm, it slips into your pack without a fight. The extended length (up to 2 m) means taller campers finally get a bag that fits.
