Sea to Summit Spark Daunenschlafsack

If you count every gram but still want a good night's sleep, the Spark is probably the right sleeping bag for you. Filled with RDS-certified goose down with 850+ fill power treated PFC-free with Ultra-Dry Down, the Spark is equipped with a technical hood and a zipper cover to retain warmth. For comfort, the super-breathable interior is made of 10-denier nylon, while the 10D exterior with PFC-free DWR coating and a highly water-repellent hood and foot box keep out wind and condensation. The model with continuous side zipper can be combined with an equivalent Spark Women's so couples can share the comfort.
