Compact, lightweight and technical - the Spark Sp2 Sleeping Bag from Sea to Summit is ideal for trekking in spring conditions, cycle touring or adventure racing.

Featuring a contoured mummy design with extra room for your shoulders and hips without compromising on thermal efficiency, the Spark also has a 10D nylon shell and 7D lining to keep the weight to a minimum. For insulation, it’s filled with RDS certified 850 Loft Premium Goose down which has an ULTRA-DRY water-repellent treatment to protect it from moisture. The ½ zip with two sliders allows you to access the Spark, and ventilate from the mid-section if necessary.

With a 4°C comfort rating and -2°C lower limit this bag is ideal for mild spring and autumn expeditions. The vertical chest baffles prevent the down moving around, the horizontal sewn through baffle construction keeps the weight down, and the draft tube prevents heat from escaping through the zipper.

For fast and light adventures, the Spark Sp2 will keep you comfortable while your sleep without having to compromise on space and weight.
