Built with gravity-focused riders in mind, the Osprey Packs Raptor Pro 18L Backpack is the ideal pack for laps at the park, long days in the backcountry, and machine-groomed trails. It features a D30 CE Level 1 back protector to help absorb shocks when an unwanted crash comes your way. A hydration sleeve with direct-zip access and hose path provides easy loading and includes a 2. 5L reservoir. All of your gear will fit easily in a wide variety of pockets, ranging from secure side panel pockets for leg/arm protection storage to mesh zippered pockets on the hipbelt for your smaller items.
