Sea to Summit - Spark -18°C Down Sleeping Bag - Down sleeping bag

Down sleeping bag for winter outdoor adventures

The Spark -18° down sleeping bag from the outdoor specialists at Sea to Summit is a lightweight, yet very comfortable, very warm sleeping bag for winter camping. With a lower limit of -18° Celsius and a comfort temperature of -10°C, this sleeping bag is ideal for winter - at least if you're not travelling too far away! When unfolded, it can also be used as a blanket to keep you cosy and warm. The generously sized foot box also leaves you plenty of room in the feet area. The technical, comparatively large hood offers you both the best insulation performance and cosy comfort. Plus, the Spark -18° can be combined with women's specific sleeping bags and quilts from Sea to Summit. An ergonomically-shaped draught collar offers extra protection from the cold.

First-class choice of materials and workmanship

The outer material of the Spark -18° is both water repellent 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 - all the more so with a fill weight of 945 grams! 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. Last but not least, the sleeping bag is designed with a relatively close-fitting mummy cut, which is intended to maximise thermal efficiency.
