Product Description

The Ultra 10°, the lightweight in our Ultra series, is primarily intended as a sleeping bag liner or as a hut sleeping bag.

It features a quilted design in which its filling of the highest quality goose down with 850+ cuin fill power is quilted into individual chambers to prevent down shift.
However, the focus of the Ultra 10° is not only on the inner workings, only the finest of the finest is used in the manufacturing process. Pertex Quantum is applied as the shell and liner fabric, which is made entirely of recycled polyamide.

Components such as the zipper and webbing, on the other hand, are made from recycled PET bottles.
Due to its light weight, the Ultra 10° is the fulfilment of all lightweight dreams. The pack size is about the size of a 1-liter bottle, so the Ultra 10° can fit in small packs.
Therefore, in addition to users who are looking to use it as a liner to boost their 3-season sleeping bag, it is also aimed at the fast & light faction.

In short, the Ultra 10° is also the ideal choice for those looking for an extremely lightweight and pack-friendly companion for summer activities.
