The FLOW Race Saddle Bag S is an aerodynamic, lightweight companion to have with you when you are on a quick trip or when you don't have a lot to carry. At a 0.4L capacity, it's the perfect size to carry your favorite multi-tool, some tire-changing levers, and a tube. It contains two side pockets on the inside that are made of mesh, so you can safely and securely store your keys or money clip. The FLOW Race saddle bag attaches to your saddle rails and seat post for a firm attachment. It features a splash-proof material and a welded design, so your contents will stay dry and dirt-free!
