TECHNICALDETAILS
- ULTRA-DRY 850+ LOFT DOWN: The highest-performance down used in all Sea to Summit sleeping bags. The 850+ loft indicates that one ounce (30 g) of down will re-expand to over 850 cubic inches when compressed. A higher loft means that less down can be used to achieve the same temperature, which is important for high-performance sleeping bags. Loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) - a copy of the certification is supplied with every Sea to Summit sleeping bag. The down is responsibly sourced, RDS-certified and treated with the environmentally-friendly Ultra-Dry Down treatment.
- QUILTLOCK SYSTEM: The QuiltLock system uses the snap locks at the shoulder and foot ends of Sea to Summit sleeping bags, as well as the comforter footbox and comforter straps to secure a comforter to the sleeping bag. This adds thermal performance and versatility to your sleeping system: your integrated comforter now works for ultralight summer adventures and turns your three-season bag into a four-season sleeping system.
- RESPONSIBLE DOWN STANDARD (RDS): All the down used in our sleeping bags and comforters is independently certified to the Responsible Down Standard (RDS). The RDS standard certifies down against animal welfare requirements and tracks it from source to final product. The purchase of RDS-certified products demonstrates the demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is RDS certified.
