The ArroWhere Backpack Cover means that you can wear a cycling backpack and still be visible. The backpack cover is so visible from behind that some riders do not wear a high visibility jacket with it during the day. The unique, patent-pending design allows the rider's backpack to still be accessible with the ArroWhere Backpack Cover on. This means that you can easily get objects in and out of their backpack without the hassle of taking the entire cover off. It's high visibility yellow and is 100% polyester and water-resistant.
