For nights under the stars in the colder months, the Circuit Down -9°C Sleeping Bag from Sea to Summit has been engineered with warmth and functionality in mind. Its 650+ fill power Ultra-Dry Duck Down provides reliable insulation, while the thermally efficient wider cut gives you plenty of space to move, making it particularly comfortable for side sleepers.

A wraparound zip gives you plenty of control over ventilation, letting you open the footbox when temperatures rise or unfold the entire bag into a flat quilt, making this a truly multifunctional piece of gear worth having in your locker. Hybrid box-baffle construction helps prevent down migration and cold spots, and a shaped collar and continuous down-filled draft tubes help retain warmth during cooler nights.

Other handy features include a YYK #5 coil zipper with anti-snag plough ensures smooth, jam-free operation, and an internal, insulated pocket for your phone ensures it doesn’t get too cold in the night, too. The lightweight fabric and malleable down make this bag extremely packable, rounding this bag out as a versatile choice for camping, backpacking and van-life.
