I have the Damier 50 and I absolutely love it!!
I carry it as hand luggage and it looks so glamorous (even when I'm going for boring business meetings, it cheers me up ) and I love the glances I get at the airport, I have to admit it.
I carried it a couple of times as "normal" bag with my office laptop too, and keeps ok and has room for everything...
The only minus point is that, sometimes I put so much inside, that without the shoulder strap becomes to heavy and quite difficult to be carried around but I have absolutely no regrets, I love it!!!
no regrets. I've used my keepall 55 twice so far after purchasing it on oct. 31st, 2006. It's great to fit all my junk that I tote back and forth from nor. cal to so. cal. and it fits in the overhead compartment on the airplane. I would like to get more use out of my keepall. In time I will! but as of now... stuck studying and not traveling.
I love my monogrammed keepall. It is THE perfect weekend bag...holds everything and makes me feel oh-so-chic! I've even checked mine a few times-it still looks great.
