Constructed with a focus on sustainable production and recycled materials, the Ultra series uses the highest quality 850 RDS-certified white goose down that gives excellent, uniform thermal performance and feels like you're sleeping on a cloud. 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. Pertex Quantum is applied as the shell fabric, which is made entirely of recycled polyamide, and components such as the zipper and webbing are made of recycled PET bottles.

The Exped Ultra -10° is a high-end sleeping bag for those trekkers, fast and light adventurers, and hikers who are looking for the smallest packed size, lightweight sleeping back on the market.
