MONT HELIUM 450 SLEEPING BAG – XL – VERTICAL BAFFLES

Maximise your pack space with a compact, light weight and versatile Helium 450 sleeping bag. A 3 to 4 season ultralight sleeping bag, proven popular with hikers in a range of climate from coastal walks to sub alpine elevation. The 450 allows temperature regulation with dual zippers and offers incredible warmth-to-weight thanks to 800+ loft down. With Radial Arc Baffle System on horizontal baffles maximising loft to height and warmth. The Radial Arc Baffles curve naturally around your body rather than bending around your body. When a down baffle (chamber) is bent or distorted, ripples in the fabric occur which will compress down and create cold spots, reducing this increases loft and warmth.

Ultralight shell fabric and high-loft down fill on the Helium bags means 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 reilience, higher loft and better warmth in damp conditions.
