Built for 3+ hours of riding and offering plenty of organization options, the Osprey Viper 13 hydration pack totes your gear plus 3 liters of water for your extended rides. Hydration system features a 100 fl. oz. reservoir that conforms to back's shape even when full, resulting in a precise, stable and comfortable fit. Rigid spine/handle stabilizes the reservoir, making it easy to slide it into its dedicated compartment; large mouth makes filling/cleaning easy. Hydration reservoir pocket has zippered access that extends onto shoulder strap, letting you remove, refill and replace reservoir and drink tube quickly and with minimal fuss. Low-profile padded mesh back panel and mesh shoulder straps offer next-to-body comfort; sternum strap has a magnetic attachment for keeping bite valve accessible. Large zippered main pocket with tool organization sleeves and a mesh pocket is ideal for carrying pumps, bike tools and tubes. Front zippered pocket has additional mesh pockets for more organizational options; key clip secures keys. Stretch mesh front and side pockets work great for stashing extra gear or water bottles for quick, easy access. Quick-access top zippered pocket is lined with a soft, easy-to-clean heat-embossed fabric that helps keep sunglasses or other fragile items from getting scratched. Quickly attach a helmet to the Viper 13 with the LidLock(TM) helmet clip; bungee on the exterior of the pack allows easy adjustment of the LidLock feature. Shove-it pocket can be cinched down to secure bulky items like a jacket. Top and bottom side compression straps help stabilize pack and contents; removable webbing waistbelt helps stabilize pack. Reflective trim increases visibility in low light.

With the super-comfortable Osprey Viper 13 Hydration Pack on your back, you'll be able to tote along the day's essentials and even have some room left over for less-crucial items, like anti-venom.
