This ultra-lightweight V8 YDR 4.5 hydration backpack is designed for storing your essentials, such as your driver’s license, inner tube, tools, or even your light jacket and keys.
With its support and comfort, it will be forgotten during your outdoor outings (mountain biking, hiking or running, trail, roller, carver). The new version of the YDR 4 family is logically called YDR 4.5. The difference is in the details compared to the old version.
The minimalist hydration bag YDR 4.5 seduces with its sober and clean side. He keeps the same characteristics as his brothers, with only changes: color and water-repellent material.
In short, a revisited bag with a better fit, more breathability, more weatherproof and lighter.
