The Varo Backpack is for the true “all weather” cyclist, because this roomy backpack is made from 100% waterproof nylon. The handy roll closure keeps the rain out of the bag. The bag has adjustable hooks and detachable shoulder straps. Simply take the bag off your bike and wear it on your back! The bag has an extra inner laptop compartment and obviously it also has reflective elements for increased safety.
