Responsibly Sourced Down

Sea to Summit only use down certified and sourced by the Responsible Down Standard, an organisation that oversees the ethical harvesting of goose and duck down through independent, third party audits and checks throughout the entire down supply chain. This ensures that the down in your sleeping bag is from a bird that was never force fed or live plucked, and was treated well throughout its life.


Ultra-Dry Down

Not only is Sea to Summit’s down insulation responsibly sourced, it also has a nano-level, permanent treatment, ensuring that it’s water-resistant, antibacterial and antimicrobial. That means higher rates of longevity, increased durability and hygene, plus your sleeping bag will dry 60% faster than one with untreated down. 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, so you know it’s good!


2D Permashell

Sea to Summit’s 2D Permashell Fabric is made from high-density 33 denier woven Nylon. It’s down proof by construction and highly vapour permeable, meaning it dries fast and breathes well. It also has a DWR coating to stop water soaking into the outer layer of the fabric.
