So, I'm getting ready to go back to school in October. I'll be going to the Art Institute and for my first year (I think) most of my classes will be fundamental art classes, but my second year I'm guessing I'll be needing to get myself a laptop (I'm a Web Design/Graphic Design major) and I'd like to get an nice bag to carry all my school stuff then. Do any of you guys have a Cabas Mezzo that you use for school/work and use it to carry around a laptop (I'm getting a 15.4" MacBook Pro)? Do you think it's sturdy enough to hold that along with maybe a few books, large wallet, keys, small make-up case, etc? Thanks in advance!
