23L–35L Expandable Motorcycle Tail Bag with Waterproof Inner Liner and Helmet Storage

Carry more without committing to a bulky fixed-size case. This motorcycle rear seat bag holds about 23L in its compact form and expands to 35L when you need extra room for longer rides. Its structured shell helps the bag keep its shape, while the removable waterproof inner liner protects packed gear from wet weather when properly closed. In expanded mode, the storage space is large enough for many full-face helmets. Rhinowalk Official Store
