Nashbar Waterproof Rear Panniers. Showing up at the end of your commute or touring day only to find soggy sandwiches, cellphones, clothes, and shoes is the bummer of all bummers. Avoid this cycling fiasco with Nashbar's Waterproof Rear Panniers. They are made with rugged 400 denier nylon which is scuff, puncture, and tear resistant, and treated with EPU coating on the inside which seals the deal literally. A roll top closure makes it impossible for water to work its way in...you pretty much have to throw these panniers in a river to get your stuff wet. With a whopping 31 liters of capacity, you can hit the road for months with these panniers. For the ultimate all weather touring capacity, we recommend pairing these with Nashbar's Front Waterproof Panniers which are a smaller version of this item.
