Product description
Ultralight and warm mummy sleeping bag
The Spark Spl mummy sleeping bag from Sea to Summit is are not only ultralight weight and extremely packable but also incredibly warm. The design reflects the demand to defy the most diverse weather conditions with a sleeping bag that is as light as possible.
Water-repellent down fill for an optimal fill power in damp conditions
To ensure that the fill power and the thermal insulation are retained even in damp conditions, the down is equipped with a water-repellent treatment. This ensures that the goose down retains its shape and does not collapse and clump together when wet. In addition, the sleeping bag is equipped with the extra-light YKK #3 zip as well as a shell made of 10D nylon and a 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.
Vertical baffles at the chest to prevent cold spots
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.
Ideal for demanding and lightweight adventures
Thanks to its incredible design and excellent features, this sleeping bag is a solid option for lightweight adventures in places where down has never really been a viable option before.
The features at a glance:
- Very lightweight mummy sleeping bag for lightweight outdoor adventures
- Water-repellent down fill for the best possible insulation at a relatively low weight
- Vertical baffle construction at the chest for an optimal distribution of the down to prevent cold spots
- Very compressible and to compactly store it in your backpack or luggage
