Always ready for what lies ahead, the Ortlieb Sport-Roller Free Panniers are packed with waterproof goodness, and the space you need to load up for a quick get away. They pack in 25-liters of storage space, and an integrated interior pocket for staying organized, making them ideal for either your daily commute, or packing up for a light bike tour. Outside they are crafted from burly polyurethane-coated polyester that shields your gear from the elements, without the use of PVC. It mounts securely to nearly any pannier rack with a tube diameter of 16-millimeters or less, and comes along with adapters for running on bikes with 8, 10, and 12-millimeter tubes, while fighting scratches on your rack. Should your ride take you through dim alley ways, or shady canyon roads, reflective Scotchlite patches shine brightly under headlights to help you stay visible as you make your way on your adventure.
