Down is considered the best insulation available, but when wet it quickly loses loft and the ability to keep you warm; 800-fill-power DriDown is treated to resist moisture. Proprietary process treats each individual duck down plume with a molecular-level polymer so the down stays dry longer, lofts better and dries faster than untreated down. DriDown insulation stays dry 10 times longer, retains 170% more loft when exposed to moisture and dries 33% faster than untreated down. Ripstop polyester exterior endures repeated use in the outdoors; polyester taffeta lining is soft and comfortable next to skin.
