Sea to Summit - Spark -9°C Double - Down sleeping bag

Versatile, down double sleeping bag for outdoor adventures

The Spark -9° down sleeping bag from the outdoor specialists at Sea to Summit is a lightweight, yet very comfortable, very warm double sleeping bag for camping and outdoor adventures. With a lower limit of -9° Celsius and a comfort temperature of -2°C, this sleeping bag is certainly more suitable for the cooler times of the year, even in winter. However, it can also be used as a blanket should the weather become too mild. The double mummy sleeping bag is perfect for cosy togetherness in a tent or van when it's really nippy outside, but can of course also be “used" alone, in which case it offers one person loads of space!

Adjustable hood and spacious foot box

The generously sized foot box also leaves you plenty of room in the feet area. Meanwhile, the technical, comparatively large hood offers you both the best insulation performance and cosy comfort. Plus, the Spark -9° can also be combined with Sea to Summit quilts. Lastly, an ergonomically-shaped draught collar offers extra protection from the cold.

Premium choice of materials and workmanship

The outer material of the Spark -9° 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.
