I tried both sizes on...I'm vertically challenged so the 22cm is just perfect. I was extremely surprised how much I liked how the bag hung on the shoulder. The best part is the strap...it is extremely sturdy and adjustable. Nice thickness. They did a great job designing this bag. It's one of those bags that you have to try on...like the Gao. Just looking at pictures does absolutely nothing for this bag. IRL it's 1000x better. It's a must try. The only thing is the price. The 22cm is about $5k, but with a finished interior (not linen), the price point makes sense. btw, it's NOT slouchy at all as it stands quite structured on its own.
