Not all motorcyclists ride when it’s raining. However, if you’re an all-weather rider, then a small commuter sized all-weather backpack might be of interest. The Oxford Aqua 25R Backpack has been designed with a top opening, roll-down closure system with seams that are electro welded to ensure the backpack is waterproof. Construction material is tear resistant and waterproof Tarpaulin. Carry capacity is 25 litres (6.6 gallon) and the backpack is available in white or fluro yellow.
