Sea to Summit - Spark -1°C Down Sleeping Bag - Dunsovsäck

Versatile, compact down sleeping bag for all your outdoor adventures

The Spark -1° down sleeping bag from the outdoor specialists at Sea to Summit is the Swiss Army knife of sleeping bags! With a lower limit of -1° Celsius and a comfort temperature of 4°C, this sleeping bag is certainly more suitable for the cooler times of the year, even if not for really harsh winters.

The mummy sleeping bag offers a fitted cut, while still leaving you room thanks to its generous foot box. The technical, comparatively large hood offers you both the best insulation performance and cosy comfort. Lastly, an ergonomically-shaped draught collar offers extra protection from the cold.

First-class choice of materials and workmanship

The outer material of the Spark -1° is both waterproof and breathable, ensuring extra comfort both inside and outside of a tent. In addition, the RDS-certified goose down insulation boasts a fill power of 850+ cuin, which ensures top-class thermal performance. The down has been treated with Ultra Dry Down technology so that it has greatly improved water resistance and continues to warm even in damp conditions and does not lose its fluffiness so quickly either. This sleeping bag features an intelligent baffle construction that has been adapted to the human anatomy, which ensures optimal heat distribution.
