Oh, you're talking about to Soho satchels that were released earlier this year.
I bought the large one in white with brown handles, and was heartbroken when the handles started bleeding brown onto the bag. *sniffle* So I had to return it.
As far as I know that bag should be pretty durable. The leather is good quality *like all Coach
leathers* and with the dark color it won't show dirt or wear easily. My satchel had no problem going on my shoulder, and I'm not a small girl, so you shouldn't have any problems with the smaller one fitting I shouldn't think.
