Perfect for trekking, long-distance hiking, mountain touring and bivouacs. For all those who are looking for a lightweight sleeping bag with the widest possible range of use. With the Ultra -5°, the pack weight can be reduced to an absolute minimum. The filling of finest, RDS-certified goose down with 850+ cuin fill power gives it an excellent, uniform thermal performance. The circumferential, I-beam down baffles allow the down to be shifted as needed, adapting the sleeping bag to the given outside temperature and the sleeping mat being used. However, the focus of the Ultra series is not only on the filling, Exped also employs only the finest of the finest when it comes to manufacturing. Pertex Quantum is applied as the shell fabric, which is made 100% of recycled polyamide. Components such as the zipper and webbing are made 100% of recycled PET bottles. The Ultra sleeping bag features the intricately designed, comfortable 3D triangle footbox, and the zipper flap prevents unpleasant cold spots. The adjustable elliptical draft collar nestles around the neck, minimizing draft and heat loss.The Ultra sleeping bag is available in five different sizes - so anyone can find the right option!
