The Mountain Equipment GLACIER 1000 REGULAR is your reliable companion for frosty nights in the high mountains or winter bivouacs. With 1000 g of DOWN CODEX-certified duck down (minimum 700 cuin fill power), it keeps you reliably warm even at -25°C. The water-repellent, lightweight 30 denier DRILITE® LOFT™ outer material made from recycled polyamide protects against snowfall and condensation – perfect for changeable conditions in tents or snow caves. The ingenious chamber construction with trapezoidal upper chambers and slanted box chambers on the underside prevents cold spots and ensures optimal heat distribution. Six chambers in the anatomically shaped foot section keep your feet comfortably warm, which is especially important in low temperatures. The five-chamber hood also guarantees even warmth. The long Gemini™ zipper is extra reinforced, prevents snagging, and keeps the warmth securely inside the sleeping bag thanks to its system. The magnetic Lode Lock™ closure and the drawstrings on the thermal collar are easy to operate, even at night. The Alpine Fit is slim without compromising on comfort, optimizing the warmth-to-weight ratio. In addition, not only the outer material but also the inner material is 100% recycled – an ecological plus point. If you are looking for a warm, functional, and sustainable sleeping bag for extreme cold, the Glacier 1000 is the perfect choice for your next winter trip.
