Hi, I previously owned two 22 Mini bags, but unfortunately, neither worked out for me. There were two main issues. First, the straps on mine weren’t removable, which limited how I could wear them. Second, as you pointed out, the bag doesn’t have a true closure. When not fully scrunched, the top remained open and everything inside was visible, it just looked sloppy and unfinished. I shortened the strap, since it was too long for me, by tying it inside the bag with a small adjustment ring. But because the bag stayed open, I really disliked looking down and seeing the visible mess where the strap was tied. It just didn’t look neat or polished. While scrunching helped somewhat, I didn’t like how the bag looked worn cross-body that way, and I was also concerned that repeated scrunching might eventually damage the leather edges where the chain enters the bag. I wasn’t too worried about security since the bag sits in front of you when worn cross-body, but realistically, someone could still easily slip a hand inside.
I’ve never heard of the 22 minis coming out with any type of closure, as mentioned in the comment above, if they did, I’d probably reconsider and get one again.
