Daily Commuters who cycle in all weather, including heavy rain

Urban Riders carrying work, shopping, or travel essentials
Night Cyclists who value high visibility and safety after dark
Wet commutes can quickly become stressful when you are carrying work essentials, shopping or spare clothing. This 20L waterproof bike pannier bag uses welded tarpaulin construction and a roll-top closure to help keep your belongings dry during rainy rides.
Adjustable top hooks and a 360° movable lower mount allow a more secure fit on a wide range of rear racks, helping reduce unwanted movement while cycling. When you reach your destination, the quick-release system, carry handle and included shoulder strap make it easy to remove and carry away from the bike.
High-frequency welded construction helps create a sealed waterproof barrier without exposed needle holes. The roll-top closure provides additional protection during wet commutes and changeable weather.
The 20-litre compartment offers practical space for work essentials, clothing, groceries and touring gear. The roll-top design can be adjusted around different loads while keeping the bag compact when carrying less.
Adjustable upper hooks can slide sideways to suit different rack layouts, while the 360° movable lower mount helps improve positioning and stability. The quick-release design allows fast attachment and removal without additional tools.
Use the built-in handle for short distances or attach the included shoulder strap when commuting, shopping or travelling. The non-slip strap adjusts from approximately 80 to 136 cm for a more comfortable fit.
The Full-Reflective version features an all-over reflective surface that becomes more visible under vehicle headlights and street lighting, helping improve visibility during low-light commutes and night rides.
