Quiltlock system
The QuiltLock system uses pressure blocks located 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 duvet to your sleeping bag. This adds thermal performance and versatility to your sleeping system: your integrated duvet now works for ultralight summer adventures and turns your seasonal sleeping bag into a four-season sleeping system.

C0 DWR
Most of our products have already switched to PFC-free C0 water-repellent finishes and in 2023, our tents and containers will join them. Our goal is to use 100 per cent PFC-free C0 water-repellent finishes by 2025.

Responsible Standard for Pure (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.
