The Mad River is a packable down mummy bag for the backpacking traditionalist that just wants a good night’s sleep after a good day’s work. 650 fill-power duck down means this bag packs small and still lofts up tall so you can comfortably recharge after a day on the trail. Chemical-free ExpeDry™ permanently helps down dry quick and maintain loft when sweat, humidity, and condensation try to dampen the mood–and the bag’s warming powers. Full-length anti-snag zipper and secondary side-zip give you precision comfort control and blanket-like coverage for changing conditions, sleeping positions, and tent card games. Roomy footbox adds space for your feet to breathe while an insulated draft tube ensures warm air doesn’t drift out when you’re drifting off to sleep. Internal stash pocket lets you store valuables like a headlamp or contact lenses, while the included storage sack and compression sack mean this bag is ready to pack down tight from day one.
