Practical and protective, the Ortlieb Sport-Packer Plus Panniers Pair is made of tough Cordura and has a gasket under the lid to protect your gear from dust, rain, and snow. A QL2. 1 mounting system attaches to your rack quickly and easily thanks to the tool-free, adjustable hook design, and even comes with reduction inserts to accommodate racks with tube diameters of 8mm, 10mm, and 12mm. An integrated shoulder strap provides you with an off-bike carrying solution, while the highly reflective 3M reflectors bolster your visibility after dark.
