The waterproof Ortlieb Seat-Pack QR attaches to the seatpost and features the patented Seat-Lock mounting system. Durable nylon, internal reinforcement and five straps help keep the bag stable and its contents securely packed. With the 4.3 cm-wide adapter, the bag can also be mounted on a height-adjustable seatpost. The air-release valve lets you compress the contents, while the protective plate underneath helps prevent damage from contact with the tyre and also functions as a mudguard.
