Instead of dealing your gear annoyingly jostling around on your back, focus on setting a new trail PR with the Osprey Packs Duro 15 Hydration Pack. Doing more with less, this true vest-pack provides bounce-free stability and utilitarian comfort as you log mile after mile. Its tough nylon design holds up against encounters with narrow slot canyons and snagging branches, while the hipbelt wrap with zippered pockets not only stabilizes the ride, but also keeps the essentials right at your finger tips. An included Hydraulics 2. 5L reservoir with attached hose and sternum magnet frees up your hands for easy drinking when you’re in the middle of a 5K, and the zippered main compartment and multiple pockets ensure you bring along your gloves, hat, headlamp, extra layers, GPS, and any energy gels you might need during your outing.
