When I saw this on the website I read it was a large and I will be able to fit my iPhone plus in it. Turns out nope. That is the main reason I wanted it. That is my only con. I've put tools, gloves and wallet in there and it fits all snug. It was actually kind of heavy and the magnetic bracket still held it up which impressed me very much. It dosent rattle while riding. It is sleek and lives up to the timbuk2 quality you've come to expect.
