you want to get a rack and bag for your bike, really, trust me
I agree. At one time, I used a backpack. It's too much strain on the back for long hauls, and over extended periods, such as commuting day after day, year after year. Do yourself a favor, and purchase a rack with a mounting bag. There are a lot of great designs out there.
