Sea to Summit Spark -1C Regular Sleeping Bag Dark Grey Yellow Women
The Sea to Summit Spark -1C Regular Women Sleeping Bag demonstrates Sea to Summit's 100% commitment to constructing a sleeping bag that is perfect for you. The women's specific shape and body mapping result in warmth and comfort without the weight. The RDS-certified 850+ fill power goose down treated with an Ultra-Dry Down treatment without PFAS provides superior insulation, while the technical hood and zipper draft tube prevent precious heat from escaping.
A super breathable 10D lining fabric rounds out the comfort profile, and a 10D outer layer with PFAS-free DWR combined with a highly water-repellent hood and foot fabric keeps moisture out. Couples can zip the full-length female Spark to an equivalent unisex Spark for added comfort and thermal efficiency.
Features:
- 850+ fill power RDS-certified goose down with Ultra-Dry Down treatment without PFAS for maximum thermal performance
- Ultralight and breathable 10D nylon lining and 10D outer fabric with PFAS-free DWR keep the hood and foot area highly water-resistant
- YKK No. 5 zippers with puller provide reliable, snag-free operation
- Women-specific fit: narrower at the shoulders (to reduce weight) and wider between the hips and knees to allow a natural side-sleeping position
- The technical hood and anatomical footbox provide excellent heat retention without the claustrophobic feel of some ultralight bags
- The Sea to Summit warranty is offered for the lifetime of this product
