Keep up with the colder climates, in the Spark Women’s -9C Down Sleeping Bag by Sea to Summit.

An RDS certified 850+ FILL Power goose down provides both comfort when unpacked and a compact pack down, treated with ULTRA-DRY down water-repellent to protect from moisture on the damper days off the grid. Boasting a 10D Nylon construction in the shell, lining, hood, and footbox for lightweight breathability and water resistance on every outdoor retreat, this bag sports a Mummy Fit for thermal efficiency and minimal weight too. A technical hood also offers a soft-touch adjustment, sitting deep for a warmer winter-camping experience.

To minimise cold spots, vertical and horizontal chest baffles are present in both the lower-half and base, while a box wall baffle construction exists throughout the entirety of the bag. A -9°C comfort rating and -15°C lower limit also has it suitable for sub-zero temperatures on those cold-weather camping trips. A durable 3/4-length #5 primary zipper features a zip plow and two sliders, followed along the top by a down-filled draft tube. Plus, the double draft collars traps heat effectively for a toasty night’s sleep amid frosty climates.

For a sack that’s serious about sleeping well in the wild, embrace the ups and survive the drops of winter camping in the Sea to Summit Spark Women’s -9C Down Sleeping Bag.
