Thule Rail Hydration Pack – 8L MTB Pack for Enduro & Aggressive Trail Riding

Designed for aggressive trail riding and Enduro racing, the Thule Rail Hydration Pack helps you stay hydrated and comfortable on demanding terrain. Its thoughtful design places weight low and centered, promoting stability as you descend, jump, or carve tight lines. The pack integrates a magnetic ReTrakt hose that returns to its resting place, so your hands stay on the bars and your eyes stay on the trail. A 2.5L HydraPak reservoir with a slide closure ensures easy cleaning, while a locking bite valve helps prevent spills before or after the ride. The Rail system supports knee and elbow pads, a full-face helmet, or removable chin bar, making it versatile for backcountry missions and race requirements alike. For riders seeking added protection, the removable Koroyd spine protector found in the Rail 12 Pro offers lightweight shielding without weighing you down.

Stability, accessibility, and smart organization

From the moment you throw a leg over the bike, stability is the focus. The low center of gravity paired with stability rails and a linear-pull chest strap minimizes movement during aggressive descents, jumps, and tight turns. When hunger or a quick tool swap hits, the jersey pockets offer fast access, while internal pockets help you keep tools, pumps, snacks, and accessories neatly organized.
