This is the Shimano cycling backpack R16. I purchased this used, but I'm selling it because I no longer need a backpack of this size. It has been washed with laundry detergent and a reverse-type soap. The capacity is 16L, and it has a hook for hanging a helmet. The rain cover shows signs of use, but there are no holes. The left and right drink holders were originally stretched. The elastic band for securing the waist belt is also slightly stretched. There are also some scratches on the reflective material and the logo. The backpack is still sturdy and in a condition that is still practical for use.
