I'm a new commuter, I have been using a backpack to carry my laptop. I have a ton of specific gear and tools that I need to keep in my backpack for my job. I want to know if anyone can recommend a pannier that I can place my backpack inside and go. I've looked into bags that convert into backpacks but I really like my backpack and I travel often so I don't want to switch all my gear if I have to go to the airport the next day. I was looking at possibly the axiom lasalle. Any thoughts are appreciated. Thanks!!!!!!
