The opinion of Aventure Nordique

The Spark -18C/0F is the ultra-light sleeping bag in the Sea To Summit range, offering excellent performance. In Regular size, it is filled with 840 grams of 850 cuin 90/10 European goose down, with Ultra Dry Down treatment for greater resistance in wet conditions. It weighs 1115 grams for a comfort temperature of -10°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 H-shaped compartments. The hood and footbox are made of waterproof, breathable fabric.

The Spark -18C/0F sleeping bag has a 3/4-length zipper with 2 sliders and an anti-cold pad. In addition to the hood, the front and back of the neck are collared to protect against air ingress.
