If super lightweight walking or ski touring is the thing for you then the Mont Helium 600 down sleeping bag is an ideal choice. Impressively light, surprisingly compact and exceptionally warm by way of 800+ loft down.

OVERVIEW

The Helium 600 is suitable for temperatures as low as -10°C and still weighs 1kg! Ideally suited to cold weather and four season camping including use above the snowline.

Ultralight shell fabric and high-loft down fill on the Helium bags mean higher performance for less weight. Durable 10 by 10 denier, 520 thread count Nylon weighing only 26g/m2 with a hot-rolled-cire treatment to prevent down leakage and increase durability. Premium 800+ loft white down fill with DWR Loft treatment adds greater resilience, higher loft and better 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.“
Mont Ambassador and backcountry guide Doug Chatten. While the Helium 600 is rated to -10ºC, it is not appropriate for alpine snow camping unless you're an experienced alpinist.
