What Our Gearhead® Experts Are Saying: "This pack is a game-changer for gravel rides. The vest-style fit keeps it stable and comfortable, and the hydration reservoir is easy to access. With thoughtful organization and bike-specific features, it's perfect for long, unpaved adventures." We rely on the Osprey Escapist Velocity 6L Bag when the road disappears and the adventure stretches beyond the horizon. Designed with Osprey’s signature attention to detail, this lightweight hydration pack combines the stability of a running vest with the functionality of a bike pack. Its body-hugging spacer mesh harness keeps weight balanced and movement unrestricted while maintaining airflow for all-day comfort. The included 1. 5L Hydraulics reservoir delivers quick hydration on climbs and descents alike, and a removable tool roll keeps gear neatly organized for trailside repairs. Multiple mesh harness pockets let us stash snacks, gels, or a phone within easy reach, while the LidLock system secures our helmet when we’re off the bike. Whether we’re pushing deep into gravel backroads or exploring singletrack, the Escapist Velocity keeps our essentials—and our hydration—locked and loaded.
