Glacier Expedition Sleeping Bag: -31F Down

Letting the slightest amount of air of sub-zero temps into your sleeping bag can make the difference between a successful expedition and leaving early to treat frostbite. That's why Mountain Equipment instilled secure closures on the Glacier Expedition Sleeping Bag; not only does this superlight bag stay warm in sub-zero temperatures, but it also features a Gemini draft tube down the full-length zipper, as well as a magnetic Lode Lock draft collar to keep those bone-freezing temperatures at bay.

Considerably lighter than the original DriLite Loft fabric, but still with the same highly water-resistant hydrostatic head, DriLite Loft II is insanely lightweight and tough, making it the ideal choice for the Glacier Expedition Sleeping Bag's construction. Pure Duck Down 700-fill power insulation traps precious heat and offers an exceptionally high warmth-to-weight ratio, while the horizontal-running trapezoid 15:11cm baffles combine with slanted box-wall baffles to strike a balance between down control, weight, and versatility. Plus, this bag comes with a waterproof roll-top stuff sack and storage cube for easy packing and transportation.
