"There aren’t many products that come along and utterly improve an entire class of gear, but that’s what Sierra Designs managed to do with their DriDown™ line."
With DriDown, unveiled this season, Sierra Designs gives us a new option- 600-fill down that's treated with a polymer that coats to the molecular level, giving each down plume a hydrophobic finish. The result is down that, while holding on to its best-in-nature volume-to-weight ratio and insulating properties, also stays dry 10 times longer, retains 170% more loft and dries 33% faster when exposed to moisture compared with normal, untreated down.
