The Ultra -10 ° is an extremely lightweight, compact 3-season sleeping bag for those who do not compromise in their equipment selection. 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 -10°, 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 entirely of recycled polyamide. Components such as the zipper and webbing are made 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! The extremely lightweight, compact 3-season sleeping bag Features: Lightest construction with recycled Pertex Quantum shell fabric Adjustable elliptical draft collar Downshift function for enhanced warmth distribution The thick draft tube backing the YKK zipper provides excellent heat retention. The anti-snag stiffener ensures smooth operation of the zipper. The elliptical draft collar with elastic cinch cord allows the collar to be fully closed over the shoulders, keeping warmth inside the sleeping bag with reduced material bunching. The elliptical draft collar can be closed with a snap to ensure all-round insulation. The Hood and Draft collar can be cinched closed and adjusted with cords. The large zipper garage keeps the zipper head away from the face. The glow-in-the-dark zipper puller makes it easier to find.
