Wow, I cannot imagine how small they will make this micro Ant. The strap looks like it would be adjustable but when you look at the stud and the end of the strap, there doesn't seem any room to elongate it from the default length. KWIM?
I wonder if the micro will be a challenge to get your stuff in and out. I sometimes found the opening of the small Ant to be a bit tight and the zipper often scraped my hand as I reached for things inside my bag.
It would have to be a narrower, meaning not a deep, bag if it is to work as a crossbody bay...or you will have this fat structured bag banging against your hip.
