Ortlieb Seat-pack 11L

"The Ortlieb Seat-Pack 11L is the perfect addition for all those who like to go on micro adventures and want to stow their equipment safely. This versatile saddle bag can be easily attached to the saddle seat with extra strong Velcro fasteners and also serves as a mudguard in the gel end. With a waterproof design, the Seat-Pack ensures that your clothes stay dry even in adverse weather conditions. The bag offers a variable volume of 4.5 to 11 liters, which can be easily adjusted by unhooking the roll closure on the side. An integrated valve also enables quick compression so that the bag remains compact"
"The Seat-Pack is not only waterproof, but also an ideal backpackreplacement for day trips. Whether you are out and about on a mountain bike, road bike or emountain bike, the bag offers enough space for everything you need. Thanks to a protection class of IP 64, it is optimally protected against dust and splash water. The more compact version of the bag is ideal for smaller frame sizes and bikes with a lowerable seat post, as it only needs to be attached to the seat post by six centimetres."
"Make sure not to exceed the maximum load of 3 kg to avoid material breakage. It is also important to check that the bag is securely fastened before each ride to minimize the risk of injury. Make sure that the bag does not touch the seat tube clamp to prevent unintentional opening during the ride. With the Ortlieb Seat-Pack 11L you are well equipped for any kind of adventure, be it cycling, hiking or mountain biking."
