The Back-Roller Free is based on the ever-popular Back-Roller, which has proven itself millions of times. The Free line does not use PVC, but does not compromise on performance either. Through the use of robust polyester fabric, the waterproof rear pannier becomes a long-lasting companion while maintaining the same timeless tarpaulin look. And thanks to the hermetic roll-top closure, food and gear travels safely and protected from the elements.
