WATER-RESISTANT DOWN
Everyone loves down - except when it clumps into useless, non-insulating balls of frustration. In early 2012, two companies introduced products with specially treated down designed to minimize this problem.
Sierra Designs is using [a] polymer-based technology called DriDown, with a proprietary application method, in several new sleeping bags and jackets.
