I'm 5'2" and after trying on all the ergo hobos, that one fit the nicest on my shoulder, was the easiest to get on one handed and the patent is really nice. Squishy is a great adjective for the material. Plus, it smells heavenly. I didn't get to try on the red patent but if I did, I would prolly end up buying it.
The great thing about the large of the ergo hobo is it is so light weight, you would really have to fill it up to feel weight on your shoulder.
