Description
For ultralight backpackers, adventure bikepackers, and everyday campers, the Spark 30 Down Sleeping Bag is here to provide a comfy night’s sleep in a super lightweight package. Sea to Summit stuffed it with 850+ fill power goose down for the best possible warmth-to-weight ratio while also keeping us cozy in temps down to 30°F, and gave it an Ultra Dry Down treatment that maximizes thermal performance even when wet. The ultra-light, breathable 10D nylon shell and lining shed even more weight while adding durability, while the full hood and anatomic footbox wrap around the head and feet, respectively, without the claustrophobic feel of other ultra-light bags.
