Mountain Equipment Helium 400 Long - Down sleeping bag

The Helium 400 Long from Mountain Equipment is the ideal companion for camping, trekking, and travel. With its high-quality filling of 403g DOWN CODEX-certified duck down and a fill power of at least 700 cuin, this sleeping bag offers exceptional warmth with minimal weight. The 100% recycled Helium 20D outer fabric is not only lightweight and highly breathable, but also PFC-free, which reduces its environmental footprint. The innovative diagonal box-chamber construction ensures that the down remains optimally distributed and cold spots are prevented, guaranteeing a restful night’s sleep.
The Helium 400 Long’s Alpine Fit 2.0 maximizes comfort and thermal performance, while the anatomically shaped, four-chamber foot section keeps your feet warm even on cold nights. The five-chamber hood offers additional protection and comfort. The 140-centimeter-long zipper is equipped with the Gemini System, which minimizes heat loss, and the Lode Lock closure ensures easy operation even in the dark. The inner lining, made of 100% recycled Supersoft 20D, is not only pleasantly soft but also sturdy and durable.
Equipped with a waterproof stuff sack and a storage bag, the Helium 400 Long can be stowed compactly and is easy to transport. The mid-level side seams further contribute to its stability and durability. Thanks to its Good Night’s Sleep temperature rating of -5°C, this sleeping bag is perfect for trips from spring through fall. The Helium 400 Long combines comfort, functionality, and sustainability in a compact design made for outdoor adventures.
