I recently got an Assassins Creed backpack which I love dearly.
Getting and keeping it closed was an awkward thing, though.
The upper end is to be rolled up and the strap over it was held in place with a
velcro strap which got weak early. Heavily laden with all the food I need at work
it always came loose once I had it on
