Not only is PVC toxic toward the environment you love to bike tour through, but it's also harmful to your health that you've worked so hard by pedaling across the country. That's why Ortlieb made it's best-selling Rack-Pack free from PVC. The Rack-Pack Free 31L Duffel is just as outstanding as its original, as far as durability and service life are concerned. Its canvas construction includes a PU-coating to bead any water off the exterior, and the roll-top closure further reinforces the Rack-Pack's protection against water during the rainy sections of your bike tour. The Rack-Pack can clip into Ortlieb's Back-Roller or Sport-Roller panniers to further secure your load as you take on the country's roads.
