The Story
Mont Helium 680 -6°C to - 12°C Down Sleeping Bag
The Helium 680 stands as the warmest option in the Helium range, designed to keep you comfortable in temperatures down to -12°C. It is perfect for cold weather conditions and year-round camping, including adventures above the snowline.
The Helium bags feature an ultralight shell fabric combined with high-loft down fill, delivering exceptional performance while keeping weight to a minimum. Crafted from durable 10 by 10 denier, 520 thread count nylon that weighs just 26g/m², the fabric is treated with a hot-rolled-cire finish to prevent down leakage and enhance durability. Filled with premium 800+ loft RDS white down treated with DWR Loft, this sleeping bag offers improved resilience, loft, and warmth even in damp conditions.
While the Helium 680 is rated to -12ºC, it is for the experienced alpinist. If you are a cold sleeper or just starting your alpine journey we recommend the Brindabella XT.
