Waterproof 27L pannier bag for rear bike racks. Roll-top design, reflective panels, and internal organisers make it ideal for cycling, commuting, or touring.
This waterproof 27L pannier bag is built for cyclists who need reliable storage in all conditions. Whether you're commuting, bikepacking, or touring long distance, this rear rack bag offers protection, space, and durability. With a flexible capacity of 20 to 27 litres, it adapts to your load while staying secure and streamlined on the ride.
Made from high-grade 840D and 420D nylon with a waterproof coating, it keeps your gear dry in wet weather. The roll-top closure eliminates the weak points of zippers and creates a tight, rainproof seal. The interior features stratified compartments for separating tools, clothing, electronics, and other essentials. It’s easy to pack, clean, and maintain, even after muddy trails or rainy commutes.
Reflective elements on the sides and back increase visibility in low light, enhancing safety on night rides or early starts. The anti-fouling fabric resists dirt and oil, and wipes clean with ease. Installation is quick with secure side-release buckles and a bottom swivel bracket that fastens tightly to your rack. The compact footprint prevents sway while riding, and the structured shape makes loading simple.
This one-sided pannier fits most standard bike racks and is available in black or yellow. It’s perfect for urban commuters, weekend explorers, or anyone who needs waterproof storage with minimal hassle.
