Embrace the ups and survive the drops of winter camping, with the Sea to Summit Spark -9C Down Sleeping Bag.

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. 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. A technical hood also offers a soft-touch adjustment, sitting deep for a warmer winter-camping experience.

A -2°C comfort rating and -9°C lower limit also has it suitable for sub-zero temperatures on those cold-weather camping trips, embellished with a durable 3/4-length #5 primary zipper. Its zip plow features two sliders, followed along the top by a down-filled draft tube, while the standard front collar draft helps to trap heat. Plus, 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.

For lightweight sleep gear as compact as it is comfortable, the Spark -9C Down Sleeping Bag by Sea to Summit keeps up with the colder climates.
