Hey guys! I bought a MacBook Pro 15" base model (non-retina) and I'm searching for a good bag pack. I'll need to take the MacBook with me for at least 3 years almost every weekday. I'll be going to university by train and subway every day. I need a very durable bag that'll fit AND protect my MacBook. I already have the Tucano Elements sleeve and would like to be able to keep that on my laptop (so laptop -> sleeve -> bag pack). Of course it has to look good too and there has to be room for some books and other stuff! Hope you guys can help me out Thanks!
