Stay hydrated without slowing down on treks or bike rides with the Thule Vital Hydration Pack. This nylon backpack features a low center of gravity that helps improve bike handling and reduce muscle strain, and a cargo storage that provides ample space for small essentials like food, clothing, and tools. The hands-free ReTrakt hose return system lets you stay hydrated on the go, while the tail light attachment ensures visibility in low-light conditions. Moreover, the jersey-style pockets offer convenient storage, and the interior zippered pocket keeps your phone, keys, and other important items secured. Thanks to the sternum strap, this lightweight backpack delivers a stable and comfortable ride on any terrain.
