The streamlined Osprey Viper 7 hydration pack is ready to ride. It offers 2 liters (70 fl. oz.) of liquid capacity and the perfect amount of gear storage for short singletrack adventures. Padded mesh back panel and mesh shoulder straps offer next-to-body comfort; magnetic attachment on the sternum strap keeps the hydration tube's bite valve easily accessible. HydraForm(TM) reservoir system sandwiches an anatomically-shaped plastic sheet between a layer of nylon fabric and the reservoir back. Rigid spine on the reservoir stabilizes the load and makes it easy to slide the reservoir into the dedicated pack compartment; large mouth makes filling and cleaning easy. BPA- and PVC-free reservoir does not retain tastes or odors and features AquaGuard(TM) antimicrobial formula which inhibits bacterial growth. Large zippered main pocket with tool sleeves, key clip and mesh pocket carries pumps, bike tools and tubes. Front zippered pocket is lined with a soft, easy-to-clean heat-embossed fabric; small elastic mesh pocket on shoulder strap fits a cell phone or small media player. Quickly attach a helmet to the Osprey Viper 7 hydration pack with the LidLock(TM) helmet clip; bungee on the pack exterior allows easy adjustment of the LidLock clip. Bungee compression system on front of pack lets you easily secure a jacket or other lightweight, bulky items. Reflective trim increases visibility in low light; integrated rear blinker attachment strap lets you attach your light for enhanced visibility. Closeout.
