The new Seat-Pack M retains all the key features of our original Seat-Pack but in a more compact form. Requiring only 6cm of seatpost for mounting, the Seat-Pack M is perfect for smaller bikes or applications where additional clearance is required. Seat-Pack M fastens securely to the seat post with strong Velcro mounting straps, compatible with saddle rails of almost any bike. The Seat-Pack M has a maximum capacity of 11 litres with a roll closure and a compression valve to let out excess air when packing contents. Robust fabrics, custom stiffeners and an optimised strap design ensure the Seat-Pack performs in harsh off road conditions.
