ULAC Radtail Pro 1.0L

ULAC Radtail Pro

The essentials, tucked neatly under your saddle.

Designed with daily commuters and fitness riders in mind, the Radtail Pro gives you just enough space—1.0L—for tools, a tube, levers, and a snack or two. Lightweight and low-profile, it blends seamlessly under your saddle without interfering with your ride.

Built tough with waterproof nylon and a weather-resistant zipper, it borrows its clean look from the Nomadpak and Coursier lines. Inside you’ll find a mesh pocket for tidy storage, while outside you'll find two eyelets—one for your taillight, and another for extra safety or gear. Finished with ULAC’s signature triangular karabiner.
