Clean, compact, and built with all the features for a successful day on the trails, the Gregory Endo 15 Hydration Backpack boasts thoughtful organization for your tools, tubes, pumps, and extra layers, as well as a Shift RS (Ride Stability) suspension system that eliminates irritating jostling when riding at speed. This RS system lets you adjust the hipbelt vertically to sit either higher or lower on your back for an exact fit and bounce-free stability.

EVAP moisture-wicking tech in the backpanel and shoulder straps serve up cool, breathable comfort through warm temps and intense rides. Gregory made access to water a priority by including a 3D Hydro reservoir, which uses soft-molded QuickDry technology for an anatomical fit on your back, and comes ready with a DryLock bite valve for easy sipping. Molded webbing keepers hush the flapping of your straps by storing them out of sight, and a safety light lash helps keep you visible when night riding. Multiple zippered pockets—one of which uses protective foam to defend against impact and weather—safely carry all of your mountain bike essentials through the entire ride.
