Got this as an alternative to the traincases I used when I was younger. I got the medium size and it is completely perfect for my husband and myself even for week+ trips. There are pockets and dividers for everything and my regular sized bottles fit perfectly in it. I'm considering getting a bigger one to use as a portable first aid bag since things are just so easy to find in here! I love that it hangs up so I don't have to lay it down on questionable counters while camping and it just makes it even easier to see everything at once.
I have the Family size Personal Organizer that I have been traveling with for about 10 years and it still looks great. It does hold the full size bottles but I can also put my make up and hair dryer and brush all in this one bag.
My husband and I have what would now be considered the medium Personal Organizer and we have used it to travel through Europe, the US, Mexico, 8 years with the military, and the early years of traveling with our 3 children. We have finally "upgraded" to a large and have bought one for each of the kids, and a larger one for our daughter now that she is going off to college. This is the most ideal, well organized toiletries case any of us has ever seen, and the one to which we have always compared all others. LL Bean came up with a master piece when they designed these!
I wrestle alligators, sleep with tigers and once kayaked the Niagara Falls. I've taken this organizer with me everywhere and it's never failed - it just works.
