I've been recently looking for a backpack that will attach like panniers. Currently I have just been bungee cording my backpack to my rack but I am tired of this system as it takes longer to put on and take off, it doesn't attach very well and squishes my bag, and if it rains I have to put my bag in a trash bag. Since my commute got a lot shorter and i'm commuting every day multiple times I want something easier.

I want something that is more of a backpack than a pannier and it needs to be able to carry a 14" laptop safely, as well as notebooks, folders, and maybe a book. I really like something like the Arkel Bug Pannier Backpack, but I don't like the price.

I found a similar bag ::WOHO Ninja Ninja::, But I'm having problems finding reviews. I was wondering if anyone has this bag or if someone can recommend a similar bag.
