Product description

Designed to withstand various weather conditions and be as lightweight as possible, all Spark sleeping bags are not only ultra-light and extremely packable but also incredibly warm – and the Spark SpII is no exception.

Spark sleeping bags owe their incredible performance to the perfected design and premium materials chosen by the experts at Sea to Summit. They’re filled with very high-quality 850+ Loft 90/10 goose down, which has been treated with ULTRA-DRY Down to fend off moisture coming from the inside and outside. Plus, the sleeping bag is equipped with an extra-light YKK #3 zip and features a 10D nylon shell and 7D lining. When combined with the contoured mummy shape, these materials deliver efficient insulation and boast one of the best warmth-to-weight ratios you can find.

The vertical baffles at the chest optimise the distribution of the down and prevent cold spots. The side zip allows for easy entry and exit. Thanks to the optimised sizes, the sleeping bag even gives you a bit more room at the hips and shoulders to move around.

Thanks to its incredible design and excellent features, the Spark SpII sleeping bag is a solid option for lightweight adventures in places where down has never really been a viable option before.
