Product Description

VAUDE's 3-seasons quilt concept - liberating simplicity, liberating comfort. The ultra-lightweight down sleeping bag with an H-chamber construction is filled with 450 grams of high-quality 850-fill power goose down obtained in accordance with the Responsible Down Standard (RDS). Extremely lightweight and comfortable sleeping systems are possible with this quilt concept. In conjunction with your obligatory sleeping pad or air mattress, insulation at the back of the sleeping bag is superfluous - thermal insulation is provided by the mat. This not only saves weight and distributes the down fill more efficiently, it also creates more freedom of movement and comfort. Minimalists and those used to rectangular sleeping bags might forgo a hood due to weight or comfort reasons. However, to ensure a restful night’s sleep in borderline temperatures, an optional hood is included with the bag. To avoid slipping off the mat - and for the most effective heat retention - the quilt can be attached to all standard mats with hi-frequency welded edges with all-purpose clips. Belongs to the VAUDE Green Shape series.

Special Features

Responsible Down Standard (RDS)

The Responsible Down Standard aims to ensure that down and feathers come from animals that are not subjected to unnecessary harm. RDS is an international, voluntary standard that addresses animal welfare in the duck and goose supply chain and the chain of custody of down and feather material from certified farms to the final product. Individual sites are certified by independent certification bodies in annual audits. The Responsible Down Standard is owned and managed by Textile Exchange. Textile Exchange is a global non-profit organization.
