Sea To Summit Spark Sleeping Bag 7 deg. C Regular
Ultralight down sleeping bag, crafted from nylon fabric and insulated with goose down. The regular size has an overall length of 196 cm, designed for users up to approximately 185 cm in height. Mummy-shaped profile enhances ergonomic support and thermal efficiency, while still allowing ample room for a comfortable, natural sleep position. Once packed, it compresses down to roughly 2.4 liters in volume, making it highly space-efficient for trekking and travel gear.
Temperature ratings and usage conditions
The operating temperatures of the Sea To Summit Spark Regular sleeping bag are specified in accordance with EN 13537:
- T-comfort: +11 deg C - the lowest temperature at which a woman can comfortably sleep through the night,
- T-limit: +7 deg C - the minimum temperature at which a man can sleep through the night without discomfort.
durable nylon material, DWR coating
The construction of the sleeping bag incorporates ultra-light nylon fabric with a 10 denier thickness for both the shell and the inner lining. The outer surface is further treated with a PFAS-free DWR coating, which boosts resistance to moisture and minimizes the intrusion of condensation or light rainfall. This added protection ensures that the insulation remains shielded from dampness—an essential factor in preserving the thermal efficiency of the down filling.
850+ goose down fill with Ultra-Dry Down coating
Outstanding thermal performance is achieved thanks to premium 850+ cuin loft goose down, delivering an exceptional warmth-to-weight ratio. Owing to its high loft, even a modest quantity of down generates a significant insulating air layer, ensuring maximum heat retention with minimal sleeping bag mass.
Additionally, the down is enhanced with Ultra-Dry Down treatment, a hydrophobic technology that significantly reduces moisture uptake and speeds up drying time. Such innovation enables preservation of insulating capabilities in high humidity environments, all while maintaining optimal breathability and durability.
The down material carries RDS - Responsible Down Standard certification, guaranteeing adherence to animal welfare guidelines and full transparency throughout the supply chain.
YKK zipper, compression sack
Equipped with a YKK zipper featuring a zipper plow system, the sleeping bag reduces the likelihood of snagging the fabric and guarantees reliable performance, even with extremely lightweight materials. Compatibility with the QuiltLock system enables secure attachment of a matching travel quilt. Additional features include a technical hood and an insulated strip running alongside the zipper to inhibit heat loss. For convenient transport, a compression sack is included. The sleeping bag is compatible with the QuiltLock system, allowing attachment of a properly fitted travel quilt.
