650+ Fill Power indicates that 30g/1oz of down will re-expand to over 650in³ after compression. The higher the Fill Power, the more the down will insulate for a given weight. This means that less down can be used to achieve the same temperature rating. 650+ duck down provides a good level of insulation for camping and travel use. Every Sea to Summit down sleeping bag comes with a test report from the International Down and Feather Laboratory IDFL confirming the down loft and quality. All of their down is RDS certified responsibly sourced, and hydrophobically treated with a non-PFAS Ultra-Dry Down finish.
ULTRA-DRY Down™: With the introduction of water-repellent ULTRA-DRY Down™ Seat to Summit have virtually eliminated the negative effects moisture has on down. The ULTRA-DRY Down™ water-repellent treatment protects the down from external moisture and condensation from inside the bag. It is a permanent (no loss of treatment effect has been seen in over 14 wash cycles) Nano-level water repellent polymer treatment applied to Sea to Summit high loft, high quality down. The Nano-thin treatment vastly improves the down's reaction to water without effecting its weight or loft performance. ULTRA-DRY Down™ retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. Sea to Summit sleeping bags dry out 60% faster than bags with untreated down. The Nano-level treatment also inhibits bacterial and microbial growth, which makes Sea to Summit sleeping bags more hygienic and improves their lifespan.
Responsible Down Standard (RDS): The RDS is helping to shift the entire down and feather industry towards more humane animal rearing and handling practices. Overseen by the industry leading Textile Exchange, the RDS requires independent, third party assessments of all aspects of animal rearing and handling throughout the entire supply chain. By only using down that meets the audited requirements of the RDS we can have confidence that each phase of the collection process has been completed with the welfare and ethical treatment of waterfowl in mind. To find out more about how the RDS is improving animal welfare during down collection, please visit responsibledown.org (link will open a new window).
Non-PFAS Fabrics: Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with moisture, such as tent wall condensation. Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It does not affect the 'breathability' or the lifespan of the down and lasts through at least 20 washings. The down used in Sea to Summit sleeping bags is responsibly sourced. Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.
bluesign®; approved: bluesign® is the world's strictest textile standard for environmental and consumer protection in textile production, a system that provides safer and more sustainable environments for people to work in and everyone to live in. Every item that has the bluesign® approved label has been manufactured and recognised in accordance with the bluesign® standard and, therefore, produced in a resource-conserving way, with the highest level of consumer safety and a reduced impact on people and the environment (including factors such as worker health and safety, approved chemicals, carbon emission, water consumption and energy consumption).
