The Ortlieb SEAT-PACK 11L is a very practical saddle bag that can be simply attached to the seat post using very strong hook and loop fasteners. In addition to its primary function, it can also be used as a mudguard on rough terrain.

Spacious and watertight, this bag keeps spare parts dry, while it can be adapted to the load by varying its volume from 7 to 11 litres, by extending the roll-up closure on the side. An additional valve allows it to be compressed quickly and easily, making it even more compact.

For attachment to the seat post, a clearance of only 6 cm is required.
