Just wondering what people use on their daily commutes, if not on the 10 on their other bikes. I use a normal back pack but may get a laptop that I may take to work and other things. I want to get a good backpack that will protect my stuff and me while not being a 50 pound pack on my back. I've searched a little online and found the axio packs (fabric and hard packs) to be something I'm considering. Any other suggestions?
