If it ain’t broke, don’t fix it. The Mad River is a packable down mummy bag for the backpacking traditionalist who just wants a good night’s sleep after a good day's slog. 650-fill-power duck down means this bag packs small yet still lofts up tall, so you can comfortably recharge after a long day on the trail. Chemical-free ExpeDry™ tech delivers forever performance without forever chemicals, permanently helping down dry quickly and maintain loft when sweat, humidity, and condensation try to dampen the mood—and the bag’s warming powers. A full-length anti-snag zipper and secondary side zipper give you precision comfort control and blanket-like coverage for changing conditions, sleeping positions, and tent card games. The roomy footbox gives your feet space to breathe, while the insulated draft tube ensures warm air doesn’t drift out when you’re drifting off to sleep. An internal stash pocket keeps valuables like a headlamp or contact lenses secure, while the included storage sack and compression sack ensure this bag is ready to pack down tight from day one.
