Technology
Loft Loft is the volume for a given weight of down. It is used to describe the quality of down, relating directly to the insulating performance. High loft down is warmer for a given weight than low loft down. Higher lofting down will fill a larger volume of space for a given weight. As a result, less down weight is required to fill each baffle in a sleeping bag. This translates to a lighter sleeping bag. The most common measure of loft is called Fill Power. 850 Fill Power implies that one ounce of this down will loft to fill a volume of 850in3...
All Sea to Summit sleeping bags are sold with an International Down Feather Laboratory (IDFL) certificate that identifies the exact Fill Power of the down used. We guarantee our sleeping bags are filled with premium down that exceeds the stated Fill Power in accordance to the International Down Feather Bureau (IDFB) standard. - Repels moisture – Retains loft – Dries faster – Anti-bacterial and anti-microbial – Prolongs the life of your sleeping bag In a world of technical brilliance, it is remarkable that the performance of certain natural products have not been surpassed.

The problem with down is its vulnerability to water; moisture decreases the ability of the down to loft to its full potential and insulate,...
Sea to Summit is excited to announce that in 2016 all of our Sleeping Bags will use down that has been sourced and certified by the Responsible Down Standard (RDS). The RDS is a tool that is going to help shift the entire down and feather industry towards more humane animal rearing and handling practices. Overseen by the internationally lauded Textile exchange, the RDS requires independent, third party assessments of all aspects of animal rearing and handling throughout the entire supply chain process. 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. This means no live plucking and no force feeding, humane living conditions and proper animal handling, from the moment of hatching throughout the life cycle of the waterfowl, and through the entire down supply chain. In addition, The RDS will be central in helping to increase awareness...
