I need to replace my bag I use for Uni. I got my current bag as a present when I subscribed to a magazine and after a year it has holes and doesn't look to good anymore.

I need it to be a cross body bag and it has to be waterproof. It also has to be big enough to carry some books, a big waterbottle and all my other things.

Any suggestions for a brand or even a bag? I can't spend too much money, but I would like my new bag to be as fab as it can be.

Thanks for your help!
