Description

The Helium 600 sleeping bag is designed for temperatures as low as -10°C while weighing just 1kg, making it perfect for cold weather and four-season camping, including adventures above the snowline.

Featuring ultralight shell fabric and high-loft down fill, the Helium 600 delivers impressive performance with minimal weight. Its durable 10x10 denier, 520 thread count nylon weighs only 26g/m² and is treated with a hot-rolled-cire finish to prevent down leakage and enhance durability. The premium 800 loft RDS white down, treated with DWR Loft, provides exceptional resilience, loft, and warmth in damp conditions.

“If you’re heavy on experience, you’re better placed to travel a little lighter. Light on skills and light on gear decreases your safety margin.” — Doug Chatten, Mont Ambassador and backcountry guide. While the Helium 600 is rated for -10ºC, it is best suited for experienced alpinists rather than for alpine snow camping.
