Trails can be challenging enough on two feet, let alone two wheels, but the rewards of riding are infinite. That’s why we made stability a top priority when we set out to design our mountain bike packs. RS stands for ride stability, the core concept that separates Shift packs from the rest of the field. Shift RS packs feature a flexible load management system, Shift RS stability belt and include an array of internal and external features designed to create the most stable, balanced ride possible, and as enthusiastic riders we’re happy to say we achieved it! All our mountain bike packs include Gregory’s quick-drying 3D Hydro reservoir and stabilized SpeedClip integration system inside the hydration sleeve for easy installation and removal.
