Mont Helium 600 XL sleeping bag - vertical baffle

The Mont Helium 600 is suitable for temperatures as low as -10°C and still only 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.

While the Helium 600 is rated to -10ºC, it is not appropriate for alpine snow camping unless you're an experienced alpinist.
