I commuted to school for 4 years using an Arkel Utility Basket. I got the dry bag to go inside it, shoulder strap and rain cover. I held my books, laptop, art supplies and various other items great. Being in an area where it rained a lot, I always packed all my gear in the dry bag, but kept the rain cover in the top pocket. I would pull the dry bag packed full of gear out for trips to the store. Now after owning it six years there is little sign of wear.
