Sea to Summit Spark Down Sleeping Bag -9C|15F - Regular RDS
When every gram counts and the mercury drops, the Sea to Summit Spark Down Sleeping Bag -9C|15F - Regular RDS delivers serious cold-weather performance without the weight penalty that typically comes with it. Built around 850+ fill power 90/10 goose down treated with Sea to Summit's PFC-free Ultra-Dry Down treatment, this bag punches well above its 730g packed weight for three-season alpine and backcountry use. The ISO-rated lower limit of -9°C and a comfort rating of -2°C (women's) make it a capable choice for everything from high-country hunting camps to multi-day ridge walks where overnight temperatures get genuinely cold. At just 6.8 litres compressed, it disappears into your pack without compromise.
Sea to Summit Spark Down Sleeping Bag -9C|15F - Regular RDS Key Features
- 850+ Fill Power 90/10 Goose Down: High-loft down with an exceptional warmth-to-weight ratio. The 90/10 goose-to-duck ratio and 850+ fill power rating mean superior insulating performance for the 480g of fill used in this bag.
- Ultra-Dry Down Treatment (PFC-free): Down is hydrophobic-treated at the fibre level without the use of PFCs, retaining loft and insulating performance in damp or humid conditions where untreated down would clump and fail.
- RDS-Certified Down: Responsible Down Standard certification ensures the down is ethically sourced and traceable throughout the supply chain.
- 10D Nylon Shell and Liner (Bluesign-certified, RCS Recycled): Both the outer shell and inner liner are constructed from 10-denier nylon with a PFC-free DWR finish. The ultra-fine 10D fabric keeps weight and pack size minimal, while Bluesign and Recycled Claim Standard certifications confirm responsible manufacturing.
- ISO Temperature Ratings: Lower limit -9°C, comfort rating -2°C (women's), tested to the EN/ISO 23537 standard for meaningful, comparable temperature performance data.
- Full Box Baffles: Three-dimensional box baffles maintain down loft evenly across the bag, eliminating cold spots that can occur with simpler sewn-through baffle construction.
- Ergonomic Mummy Shape with Anatomical Footbox: The contoured mummy cut reduces dead air space to improve thermal efficiency, while the shaped footbox follows the natural angle of the foot to prevent compressed down at the toe end.
- Technical Hood and Zipper Draft Tube: A sculpted hood seals around the head to minimise heat loss, paired with an insulated draft tube behind the full-length zipper to block cold air ingress.
- YKK #5 Zippers with Zipper Plow: Quality YKK hardware with a zipper plow attachment prevents snagging on fabric or down, ensuring reliable one-handed operation in cold conditions.
- Zip-Together Compatibility: The full-length zipper is designed to mate with a compatible Sea to Summit Women's Spark sleeping bag, allowing two bags to be joined for shared use.
- Fits to 185cm: The Regular size accommodates sleepers up to 185cm in height.
- Packed Weight and Volume: 730g total bag weight, compressing to 6.8 litres in the included Ultra-Sil Compression Bag, making it suitable for ultralight backpacking where volume and weight are critical considerations.
- Includes Ultra-Sil Compression Bag and Storage Cell: Ships with a dedicated compression sack for trail use and a larger mesh storage cell for long-term at-home storage to maintain down loft over time.
The Sea to Summit Spark -9°C is a well-considered ultralight sleeping bag for backcountry users who need genuine cold-weather capability without the bulk. Whether you're camping out during an extended hunting trip in the high country or pushing into remote terrain on foot, this bag's combination of ethical materials, technical construction, and sub-kilogram weight makes it a serious option for three-season use.
