Description
The Ultra sleeping bag line uses first-class materials and high-quality down for uncompromising performance with minimum weight and packing volume.
The Ultra -5C is an ultra-light 3-season sleeping bag - developed for all those who do not compromise on weight, pack size, and thermal performance. Ideal for trekking, long-distance hiking, mountain tours, or bivouacs, the sleeping bag offers a wide range of uses for adventures from spring through well into autumn.
The high-quality, durable RDS-certified musk duck down ensures efficient insulation and an outstanding warmth-to-weight ratio. The adjustable, elliptical thermal collar minimises heat loss. The specially designed 3D foot box provides additional insulation in the foot area, while the side cover strip along the zip reliably prevents cold bridges.
The outer and inner materials are made from 100% recycled nylon, making the sleeping bag hard-wearing.
