If you're interested in a simple design, a full range of functions and enhanced safety at night, then you may want to consider the Ortlieb Commuter-Daypack High Visibility by Ortlieb Outdoor.The PVC-free, reflective Cordura yarn has the look and feel of a fine fabric despite being 100% waterproof.

It features a practical roll closure and hook for quick access to its spacious interior. The interior also includes a padded compartment for a notebook or tablet.The back padding is made of thermoplastic polyurethane (TPU) and is soft and free of softeners, ensuring a comfortable fit.
