Product description
Ultralight, minimal pack size and excellent thermal performance
The Spark SpII sleeping bag from Sea to Summit is not only ultralight weight and extremely packable but also incredibly warm. Spark sleeping bags owe their incredible performance to the perfected design and premium materials. It’s 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.
Optimal down distribution and light zip
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. 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 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.
The advantages at a glance:
- Ultralight mummy sleeping bag
- High-quality goose down fill
- Vertical baffles prevent cold spots
