The opinion of Aventure Nordique

The Spark Pro -1C/30F is the ultra-light sleeping bag in the Sea To Summit range, offering excellent performance. In Regular size, it is filled with 310 grams of 950 cuin 90/10 European goose down, with Ultra Dry Down treatment for improved resistance in wet conditions. It weighs 620 grams for a comfort temperature of 3°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 on the top and through seams on the bottom. The hood and footbox are made of waterproof, breathable fabric.


The Spark Pro -1C/30F sleeping bag has 3 zippers with double sliders and protective padding. One full-length on the left side, one short 1/4-length on the right and one at foot level. In addition to the hood, a collar protects against air ingress.
