Watch a video on the Traverse Series.

Designed with a relaxed mummy shape, the Traverse series offers comfort in the widest range of temperatures. With the ability to be opened out into a full duvet when sleeping in huts and zippered up for winter camping in sub zero conditions the Traverse series can be used all year round. The oversized neck-collar and hood-seal, keep drafts out, minimizing heat loss around the face. The oversized zipper draft tube is fitted with the lightest and stiffest anti-snag material, for smooth operation. A security pocket located inside the bag is easily accessible, ideal for stowing electronics to preserve battery performance in extreme cold. Using a side block baffle construction to maintain a 60/40 fill ratio more down is located in the top of the bag for maximum insulation. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep.

The Traverse series is our choice for trekking the Annapurna circuit in the Himalayas, ski touring hut to hut in the Alps and walking the Western Arthurs in Tasmania.

Relaxed Mummy Convertible
The Traverse relaxed mummy shape is cut with a larger hood, broader shoulders and large chest to provide a more comfortable sleeping bag while maintaining thermally efficiency. The addition of a full length side and foot zip allow for conversion from a traditional winter mummy shaped bag to a duvet offering the greatest versatility in a cold weather sleeping bag.
