Sea To Summit Spark SP0 Sleeping Bag (14 °C)

Technical, super compact and ultra-lightweight – the Spark Sp0 is the summer adventure bag that doubles a liner when the weather cools down.

This bag features a contoured mummy shape to maximise insulation and has a 14°C comfort rating and 10°C lower limit making it ideal for summer conditions. The Spark has a 10D nylon shell with a 7D lining and a light-gauge #3 YKK zip to keep the packed size and weight as minimal as possible.  

It’s filled with RDS certified 850+ Loft premium goose down which has an ULTRA-DRY down water-repellent treatment to protect it from moisture and ensure performance in technical conditions. This bag has a sewn through quilted construction to keep the down positioned and can be used as a liner to add more warmth to an existing bag.

With an integrated stuff sack included for storing it compactly when you’re out in the field, the Spark Sp0 is the streamlined sleeping solution for fast-paced warm expeditions.
