The end-all 'what if things go crazy' bag--800-fill goose down and waterproof-brea­thable DriZone keeps you warm to 20 below. Funk!Off liner--simply turn the bag inside-out, leave it in the light and voila, dirt and oils magically break down for a cleaner, fresher bag. Dual draft tubes, a zippered storm flap, an Expedition Jacket Hood, and fixed side baffles ensure total warmth at high altitude or Arctic temps. We weld the seams so you don't risk blowing one out due to abrasion, nor will water... less

Fortunately for you (and your partner), the Electra uses Funk!Off liner treatment, to naturally break down oils, dirt, and unidentified gunk. We've found that Funk!Off makes things considerably friendlier in snow caves, on bivies, and during tent-bound epics. On the flip side, the Electra relies on Drizone waterproof-brea­thable shell material to sit throug... less
