Mont Helium 450 -1°C to -7°C Down Sleeping Bag

A 3-4 season ultralight sleeping bag built to save weight without giving up warmth - the standard size comes in at just 850g. Hikers reach for the Helium 450 across a wide range of conditions, from coastal overnighters to sub-alpine trips, and dual zippers make it easy to vent or seal up as the temperature shifts. The result is an exceptional warmth-to-weight ratio that packs down small enough to free up real space in your bag.

The shell is a durable 10x10 denier, 520 thread count nylon weighing only 26g/m2, hot-rolled and cire-treated to stop down migrating through the fabric while adding extra durability. Inside is premium 850+ loft Muscovy duck down with a DWR loft treatment, giving it better recovery, higher loft and more reliable warmth if things get damp on the trail.
