25L waterproof bike trunk bag with roll-top seal, mesh pouch, and reflective details. Ideal for travel, touring, and cycling gear storage on rear racks.
This 25L waterproof bike rack bag is designed for cyclists who need reliable storage through all weather conditions. Whether you're commuting daily, going on weekend tours, or travelling cross-country, this rear rack bag delivers on durability, space, and function. Crafted from tear-resistant PVC mesh fabric, it offers a fully waterproof and wear-resistant shell that keeps your gear safe and dry.
The roll-top closure system provides a tight seal, preventing water from entering even in heavy rain. Unlike zippers that can weaken over time, the curled-down mouth design enhances waterproofing while making it easy to pack and unpack. The adjustable buckle allows a secure fit on various bike racks, offering compatibility and ease of use no matter the frame.
Inside, a built-in mesh pocket helps organise smaller items like maps, tools, or snacks. An external mesh panel provides a place to store wet clothes separately—a thoughtful addition for longer trips or changing weather. With a generous 25-litre capacity, there’s room for clothing, bike tools, lunch, and more, all while maintaining a sleek shape that doesn’t interfere with pedalling.
Reflective elements on the bag increase visibility in low light, making early morning or evening rides safer. A padded bottom panel protects the bag from wear when loading or setting it down, and a handy carry handle makes off-bike transport simple and comfortable.
