Sea to Summit Trek Women’s -9C/15F

The Trek Women's -1C/30F from Sea to Summit is a semi-rectangular sleeping bag that offers more space and comfort than a traditional sleeping bag. Thanks to its shape, you won't feel cramped and you'll be able to move around during the night. It has a cut specially adapted to women and a more substantial filling. It weighs 1240 grams and has a comfort temperature of -4°C.

In terms of filling, it features 520 grams (Regular size) of 650 cuin 85/15 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 of 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 Trek Women's -1C/30F 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.
