Product Description
The Ultra 0° is a feather-light and compact summer sleeping bag. It is the ideal companion for all those who do not want to give up a comfortable and fully equipped sleeping bag, even in milder conditions.

The clever "downshift" function ensures better thermal performance. Thus, the H-shaped compartments located all around allow the down to be distributed up or down as needed. This means that the sleeping bag can be adapted to the temperature conditions and the mattress used.

The three-dimensional anatomical cut of the foot location with 11 individually filled down compartments keeps the feet warm. An adjustable, well-padded cold collar keeps the heat in the sleeping bag. In addition, a double zipper flap prevents the formation of thermal bridges.

The outer and inner material is recycled and some elements such as the zipper and fabric are made from recycled PET bottles. For the filling, only RDS-certified down is used.
