I have one and I absolutely love it. I use it as a gym bag primarily. I will use it with my other travel pieces.
You must have missed this thread. http://forum.purseblog.com/louis-vuitton/ooooo-10280-3.html I have posted a picture as well. D.
My opinion, this is the best carry-on! It's like Speedy 40 but it holds lot of stuff in it. Else, get the Alize 24 Heures. Those are my favorite carry-on to date. D. P.S. The carryall fits perfectly in front under the seats in the plane. I've done it last weekend for the first time.
The Mono is like $925 or so, definitely under a grand, a great deal I think! ^^ Oh 990 thanks Pursedoc, it's on Elux periodically!
