I was thinking about suggesting this on your shoulder travel bag thread. I don't personally have a Josephine but Moynat quality is definitely there and you will pay far less than for a similar sized H bag.
Also, FWIW I have experimented "out the wazoo" with weekend bags of all varieties from LV, Prada, etc. I have finally come to the realization that it is far better, and easier on my shoulder, to use Longchamp for weekend/carryon. No worries about putting it on the X-ray belt at the airport or in the boot of the car. They are sturdy but weigh nothing, clean up easily, and when they get ratty there is no sadness in tossing and replacing with new. Their personalization program is also quite nice and offers several options for travel-sized bags, although my favorite is the zip-around-the-middle one.
