The opinion of Aventure Nordique
The Spark 7C/45F is the ultra-light sleeping bag in the Sea To Summit range, offering excellent performance. In Regular size, it is filled with 150 grams of 850 cuin 90/10 European goose down, with Ultra Dry Down treatment for greater resistance in wet conditions. It weighs 365 grams for a comfort temperature of 11°C.
The Mummy Fit cut maximizes thermal efficiency, and for the filling, Sea To Summit has opted for different 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.
To achieve such a low weight, the envelope is made of a very fine 10-denier nylon fabric, with through seams. The hood and footbox are made of waterproof, breathable fabric.
The Spark 7C/45F sleeping bag has a half-length zipper with 2 sliders. In addition to the hood, a small collar on the front protects against air ingress.
