| Responsible Down Standard (RDS) | 100 per cent of the down used in our sleeping bags and duvets is independently certified to the RDS standard (Responsible Down Standard). The RDS certifies compliance with animal welfare requirements and ensures traceability from source to final product. Purchasing RDS-certified products demonstrates the demand for best practice in animal welfare within the down and feathers supply chain. Sea to Summit is RDS-certified. |
| 850+ loft Ultra-Dry Down | 850+ Fill Power indicates that one ounce (30g) of down will expand to more than 850 cubic inches after being compressed. A higher fill power means that less down can be used to achieve the same temperature, which is important for high-performance sleeping bags. Sea to SummitThe loft and the quality/composition of the down are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every sleeping bag. The down is sourced responsibly, is RDS-certified and is treated with our PFC-free treatment Ultra-Dry Down™ . |
| Quilt Lock System | Sea to SummitThe system QuiltLock uses the press-stud fastenings on the shoulders and feet of the sleeping bags, as well as the straps, quilt / footbox to attach a quilt to the sleeping bag. This adds thermal performance and versatility to your sleeping system: your integrated duvet is now suitable for ultra-light summer adventures and transforms your three-season sleeping bag into a four-season sleeping system. |
