Mont Helium 600 Down Sleeping Bag – Vertical Baffles

-4 to -10°C

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.
