Where can I find a school messenger bag that is a surf brand?

Ok so for the past 2 years ive used this really nice roxy side messenger bag thing that worked great for carrying my books from my locker to cl & also home. It kept up great but i'm ready for a change. I got the last one from pacsun but this year they only have like 3 messenger bags. I'd really like one of the surf brands like kirra, hurley, roxy, billabong, ect. im looking for something kind of big so my books could fit in it so not really a tote & i dont want a generic type of brand like jansport. haha any help?!
