The gear experts at National Geographic Adventure have named the Sierra Designs Zissou 15 sleeping bag as a Spring/Summer 2012 Gear of the Year award winner. National Geographic Adventure selected this sleeping bag because “down is a near-perfect insulation—per-fect except for the way it stops insulating once it gets wet. That’s one reason synthetic sleeping bags are so popular in damp climes, and it’s why the new Zissou 15 sleeping bag from Sierra Designs is being heralded as the next big thing.”

DwrDown is regular down treated with a molecular level polymer that creates a hy-drophobic finish on each individual down plume.
