Duvet Ultra-Sec 750+ Loft
The second highest performing down used in all Sea to Summit sleeping bags. The filling power of 750+ means that one ounce (30 g) of down will expand by more than 750 cubic inches after compression. A higher filling power means that less down can be used to achieve the same temperature, which is important for performance sleeping bags. The 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 pressure clips placed at the shoulder and foot ends of Sea to Summit sleeping bags, along with the down foot box and down straps, to attach a down to the sleeping bag. This adds thermal performance and versatility to your sleeping system: your integrated duvet now works for ultra-light summer adventures and turns your three-season sleeping bag into a four-season sleeping system.

Women's Specific Shape
Our Women's Specific Shape bags feature a distinctive shape designed to offer more comfort and the best thermal efficiency. The models are perfectly adapted to a woman's shape - slightly narrower at the shoulders and roomier at the hips. The down distribution is perfectly adapted to ensure that the torso and feet stay warm.

Responsible Skin Standards (RDS)
All down used in our sleeping bags and quilts is independently certified according to the Responsible Down Standard (RDS). The RDS standard certifies down according to animal welfare requirements and guarantees its traceability from source to finished product. Purchasing RDS certified products demonstrates the demand for better animal welfare practices in the down and feather down supply chain. Sea to Summit is RDS certified.
