For warm weather overnights, check out the award-winning Zissou 30. Stuffed with 600-fill DriDown™ insulation, this bag gives you the light weight, compressibility, and warmth of down in a bag that will stay drier, loft higher, and dry faster in either humid or dry conditions.

DriDown™ - What it is

Simply put, DriDown™ represents the evolution of down insulation. Regular down is treated with a molecular level polymer to create a hydrophobic finish on each individual down plume. This finish allows DriDown™ to stay dry longer, loft better, and dry faster than untreated down, keeping you warmer in any environment.


Technology Explanation

It’s widely accepted that down is the best insulation available… lighter, warmer, more compressible, and more durable than any other natural or synthetic insulation ever created. But down has one major flaw. As it gets wet from rain, condensation, humidity, or sweat, it begins losing its loft and its ability to keep you warm.

DriDown’s™ hydrophobic finish is key to its outstanding performance of DriDown™, enabling sleeping bags and jackets insulated with DriDown™ to stay drier, loft better, and dry faster than bags and jackets insulated with untreated down. This means any bag or jacket insulated with DriDown™ will keep you warmer, longer in any situation.
