To keep your panniers and gear dry, rain covers are an indispensable accessory. We make them out of ultra light 1.9 oz Silicon Coated Ripstop Nylon, so they are feather light and don't take up much room. Besides keeping your panniers dry, rain covers also help keep them clean. We all know that the grit and grime that we can pick up on wet roads is some of the hardest dirt to get out. It is also detrimental to the pannier fabric. Washable rain covers help your panniers look better and last longer. Sizes available to fit all Arkel panniers and the handlebar bag.
