The largest Drift pack in Gregory 's series was born to tackle all-day epics like Moab's Whole Enchilada trail where you can start riding in a LaSalle snow squall at 11000 feet then hit 75deg and sunny at the Colorado River finish. Sized for packable layers multiple spares food and tools plus three liters of water the Drift 14 still rides comfortably all day long thanks to its Shift RS suspension.
