>>18492460 (OP)Hi OP, everyone in this thread is a retard or faggot so I thought I'd come and actually answer.
Kankens are trendy and cool among students, probably the top tier looks-wise. They're also a bit douchey - normies will for the most part think it's cool, but a very small percentage of people (autist basementdwellers on one side, truly /fa/ snobs on the other) will judge you for it.
As far as comfort, it won't beat a proper function-over-form backpack. But you're probably just wearing it for between 5 and 20 mins at a time between lectures/public transport, so you'll probably survive.
Also, you didn't need to say the books were because you were at law school. Telling people you're a law student/lawyer non sequitur is douchey too.
