The Ortlieb Back-Roller High Visibility comes from the special 'high visibility' line. The waterproof fabric in luminous neon colour reflects really well. This pannier provides very good visibility in bad weather and low light. Thanks to the handy roll closure the stable rear bag protects your belongings from water. Thanks to the mounting system you can attach the Back-Roller quickly and easily to your bike. Additionally, you can use this Ortlieb-bag as a practical shoulder bag, because it has a shoulder strap.
