Crafted for the rider who needs serious tail-storage without sacrificing style or weather protection, this Rhinowalk expandable hard-shell tail bag offers a normal capacity of about 23 litres, which can be expanded up to 35 litres enough, when expanded, to carry a full-face helmet. Available at Autonity. Its exterior is built from a stiffened EVA hard-shell design, ensuring the bag holds its shape and protects contents from impacts. At the same time, a fully waterproof inner bag (rated to PU6000 mm) with sealed seams shields your gear from heavy rain and road spray. The mounting system is designed for universal use (with four-point straps under many models), making it suitable for most motorbikes’ tail or seat rack setups. With this bag, you get a smart blend of capacity, weatherproofing and mounting flexibility ideal for everyday commuting, weekend rides or longer trips.
