Banjo Brothers' Minnehaha Canvas Grocery Bag Pannier is sized perfectly for a single paper grocery bag. It's also a natural (and vegan) alternative to synthetic fabrics. Equipped with a steel frame and heavy-duty panels to prevent sagging, this handy pannier attaches to any standard rear rack (sold separately) and folds flat when not in use. Wide, comfortable carrying handles make shopping with it easy, and if that wasn't enough, the steel hooks attach to your shopping cart. Slick. Lastly, detachable reflective accents help make sure you and your groceries are visible after dark.
