Calling All Vegan Shoppers!!!

Looking for a vegan-commuter bag...one that will fit my books, loads of (un) marked essays/tests, lecuture notes, my gym shoes, gym clothes, lunch, ipod, iBook, a rash of books that I carry for some sense of comfort.....ahhhh...help.
Due to a recent 'incident' I will not be purchasing anymore Mat and Nat, nor do I dig the new 'lug' bags...they don't fit my ibook.

Any thoughts would be wonderful...I think maybe, maybe MEC might have something for me. But I would prefer something more unique - any sewers out there???

Thanks!
