OspreyUnisex Transporter Laptop Tote Backpack (pack of 1)

I bought it, and at first I was not sure I would use it but decided to keep. In time it became my favorite bag to travel with or go to a gym. It is often rains where I live, and this bag is totally waterproof bar none. It seats well on the shoulder and very well balanced. Super comfortable packets and in right places. Fits under seats as carry on. It is shiny and looks plasticky but this where waterproof quality comes from.
