| Responsible Down Standard (RDS) | 100% of the down used in our sleeping bags and quilts 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 a 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 quilts. 650+ Fill Power means that one ounce (30g) of down will re-expand to more than 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 comes from a responsible source, is RDS certified, and treated with our PFC-free Ultra-Dry Down™ treatment. |
| Free Flow Zip | Our triple Free Flow zipper 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 the top third of the bag to be folded back to create a (mini) quilt when temperatures rise higher than expected. |
