No one can predict the weather with 100% accuracy, and on an extended tour you are sure to run into at least a little rain now and then. To keep your panniers and gear dry, rain covers are an indispensable accessory. Arkel makes them out of yellow ultra light 1.9 oz Silicon Coated Ripstop Nylon, so they are feather light and don't take up much room. An elasticized drawstring allows them to be adjusted to fit the load and piece of stretch micro mesh fabric at the bottom allows any water that gets inside to drain. 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.
