Responsible Down Standard (RDS)	100% of the down used in our sleeping bags and duvets is independently certified according to the RDS (Responsible Down Standard). The RDS certifies animal welfare requirements and traceability from source to final product. Purchasing RDS-certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is RDS certified.
650+ loft Ultra-Dry Down	This is the third most lofty down used in Sea to Summit sleeping bags and duvets. 650+ Fill Power indicates that one ounce (30g) of down will re-expand to over 650 cubic inches after compression. Higher loft means less down can be used to achieve the same temperature rating, which is important for high-performance sleeping bags. The loft and quality/composition of the down are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is provided with every Sea to Summit sleeping bag. The down is responsibly sourced, RDS certified, and treated with our PFC-free Ultra-Dry Down™ treatment.
Free Flow Zip	Our triple Free Flow zipper system allows your sleeping bag to retain maximum warmth and efficiency when needed, as well as multiple ventilation options when not. The (half) zipper on the right side of the bag (left side on women's bags) offers freedom of movement for both arms, additional ventilation, and allows folding back the top third of the bag to create a (mini) duvet when temperatures rise higher than expected.
