The description is a bit
Review by Stephanie D. on 11 Jan 2025 review stating The description is a bit
The description is a bit confusing, but it is a -1C sleeping bag. Adequate size for a multiple day hike. My boyfriend will use it during our Patagonia hike.

Excellent sac de couchage
Review by Regis S. on 26 Aug 2024 review stating Excellent sac de couchage
Vraiment un excellent sac de couchage très confortable, léger et chaud. Très compact une fois dans sa poche de compression et reprend son gonflant très rapidement. Plus large des épaules que je pensais, agréablement surpris !

Great sleeping bag
Review by Kai H. on 27 May 2024 review stating Great sleeping bag
Decided to splurge on an ultralight bag this year. It extremely light and will cut a whole pound from my pack. I also like that sea to summit has different liners to add warmth if needed rather than buy a whole new bag

Ultralight and packable performance sleeping bag with increased breathability in shell and liner fabrics.

Filled with RDS-certified 850+ fillpower goose down treated with a non-PFC Ultra-Dry Down treatment, the Spark is constructed with a technical hood and zipper draft tube to retain warmth. Comfort comes from a super-breathable 10 denier liner fabric, while a 10D shell with a non-PFC DWR plus a highly water repellent hood and footbox fabric shed wind and condensation. The full-length zipper model can be zipped to an equivalent Women's Spark for comfort that couples can share.
