I really do love the bag - one of my favorite bags was this style from LL Bean but alas they don't carry it anymore.  I'm only 5'1", and the size was just to the point that it was almost too big for me, but I knew the XSmall would be too small so I thought I'd give this a try.  Two things make this bag very uncomfortable - first It does not stay on your shoulder - the material on the underneath of the strap is smooth so it keeps slipping off, a bit annoying if travelling, I'm sure.  And then when it is full of whatever items you're carrying, it doesn't stay in the "upright" position but rather hangs like a sling under your arm...again, not a comfortable position if you want it for a travel bag.  The material is great, and the inside pockets were extremely handy, but  I will be returning it.
