I took this on a long ride and was disappointed. 1) my iPhone 7 didnt fit in the window slot, 2) when i got out of the saddle my legs brushed against it, 3) the Velcro lid blew open on a decent and contents fell out.
This is my first try using a top tube bag so some of these things may be inherent in these types of bags.
I bought the bag for food on longer rides. My Timbuktu messenger bag has been great, so I went with this top tube bag. Its too wide. My knees hit it when I get out of the saddle on a climb. I dont need the smart phone case that it has on top, so its not the right bag for me
