tagger Messenger Bags - build your own bag - eBags
I haven't bought one because I'm not in the demographic, but as a designer. I love options and this bag brand offers you options. You can mix and match as you please. I would recommend this more for teens, but if you're a cool hip adult, go for it! You can chose the artwork on the flap, the strap color and the body color. Plus you can get special markers and design it yourself. Tired of your teen drawing all over his/ her jeans? Give them a bag they can express themselves on.
