Cycle Rear Saddle Bag Waterproof Seat Bag Large Capacity Seat-Mounted for Cyclists, Commuters, Long-Distance Biking, Road Riding, Bikepacking

This high-capacity cycle bag mounts under the seat and along the seat post. It provides 13 liters of storage space for riding tools, spare tubes, and essential travel items. The bag is made from heavy-duty 500D PVC waterproof composite material with high welded construction, creating a seamless body to keep gear dry during rain. The tapered long shape is aerodynamic, and the anti-wear base protects against tire spray and friction. Multiple heavy-duty straps and buckles wrap around the seat post, with reinforced points to prevent sagging or swinging. The top closure strap allows quick access, and an external elastic cord on top can secure a light jacket or extra gear.
