Ultra Dry Down

UltraDry Down™ is a PFC-free water-repellant treatment applied to the down used in all Sea to Summit sleeping bags. UltraDry Down™ retains over 60% more loft, absorbs 30% less moisture and dries out 60% faster when compared to untreated down – which means the down will insulate better even in damp conditions. The treatment also inhibits bacterial growth, making your bag last longer.

UltraDry Down treatment is an environmentally friendly application.
