The Spark SpI-Regular sleeping bag from Sea to Summit is suitable for summer use, as well as for outdoor adventures in which weight and compactness are the priority. Superlightweight - only 340 grams, this sleeping bag features Ultra-Dry RDS 850+ Loft premium goose down, which makes the bag impressively thermoefficient and highly compressible.

The Sea to Summit Spark Series bags is what you reach for when you need a high performance sleeping bag but don’t want to be weighed down by one.

Ultra-light and technical, the Sea to Summit Spark SPI - Regular down sleeping bag (for people up to 183 cm tall) is designed to keep you as warm as possible while minimizing packed weight and size.

The secret to the impressive performance is a combination of premium materials and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics, set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation. The sizing provides extra room for sholders and hips without compromising thermal efficiency and a 1/2 zip aids access and ventilation. The down used in the Spark range is ULTRA-DRY Down - water-repellent treatment protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. 

The Spark SpI mummy sleeping bag from Sea to Summit is ideal for fast hikes in summer conditions, for use in huts and shelters, for multi-day competitions, as well as in emergency situations in alpine conditions.
