The Sea to Summit Spark -1C down sleeping bag weighs less than 600 g, even in the large version, and will keep you comfortably warm even when temperatures drop to 4°C to -1°C at night.

The -1°C limit value of the Spark -1C down sleeping bag, on the other hand, is aimed at the "standard man" and anyone who is less sensitive to the cold. The high-quality 850+ cuin goose down means that the sleeping bag can be compressed nice and small and a storage bag is included for easy storage at home. Like the other sleeping bags in the Spark series, the Spark -1C down sleeping bag has both transverse and longitudinal chambers that ideally distribute the down filling and ensure that as few down gaps as possible form when you turn over in the night.

The ergonomic hood and the warm collar ensure that as little cold as possible can sneak in and the zipper is also covered on the inside with a filled strip so that no cold bridges are created here either. Last but not least, the sleeping bag is not as sensitive to moisture with its permanently impregnated Ultra-Dry down. The Spark -1C down sleeping bag therefore offers you an ultra-light and compact way to noticeably lighten your luggage on your tours from spring to autumn, without having to forego warm sleeping comfort at night.
