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.
Sure, that emergency snake-bite kit you have is pretty rad. But during your mountain-bike ride, chances are good you're going to need access to water, an extra layer, and a tire repair patch long before you'll have to tend to a set of thin puncture wounds on your calf. 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.
