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. Stuff sack and storage sack included. What is DriDown? 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 7-times longer, retain 34% more loft when exposed to moisture and humidity, and dry 33% faster than untreated down, keeping you warmer in any environment. What is EN Testing? Going forward, Sierra Designs will now utilize the temperature that an average man or woman will sleep comfortably at which is found via EN Testing. At the most basic level, the EN Test helps us understand how much insulation is required to keep a person warm and comfortable through the night. Through EN Testing, Sierra Designs will offer authentic construction and efficient functionality to assure an overall comfortable sleep experience. For the Zissou 27, the average man will be comfortable in this bag down to 27 degrees based on EN Testing. That can vary from individual to individual; however, this gives you a solid starting point when choosing a bag.
