The opinion of Aventure Nordique
Sea to Summit's Ascent -9C/15F is a sleeping bag with a tapered rectangular shape. It's less narrow than a mummy shape, yet streamlined to keep warmth around you and save weight. Thanks to this shape, you'll be able to move around more easily. It weighs 1020 grams and has a comfort temperature of -2°C.
In terms of filling, it features 540 grams (Regular size) of 750 cuin 90/10 duck down. This duck down is treated against moisture (Ultra Dry Down) for greater resistance in wet conditions. The inner and outer shells are made from 20-denier recycled polyester.
For the filling, Sea To Summit has opted for a different type of padding according to the body's essential zones, optimizing insulation:
- Vertical padding on the torso to prevent the down from shifting.
- Horizontal padding on the bottom to minimize the weight of the sleeping bag.
The Ascent -9C/15F sleeping bag has 3 zippers with double sliders and protective padding. A full-length zipper on the left side, a short half-length zipper on the right side and a foot zipper. The hood is compatible with the brand's pillows, and a collar protects against air ingress.
