Thanks so much! I'm glad you like it! I've been dreaming it up for over a year
I'll attach photos of my bag's cinching mechanism, what it looks like from the front cinched, what it looks like from the top cinched, and my hand slipping inside to help you gauge security
It's "Ruby Red" in the Venezia leather! Here's a link to an older post of mine that shows the vibrancy of the color:

I'll also attach a photo of the swatch I originally got, which was much more Burgundy, but may better suit subtler tastes. I'm not sure what color name Marco labels this swatch - it's definitely different from the "Ruby red" of my bag!
Hope this helps you make your decision

Personally, for putting any bags under airplane seats, I like to carry around a reusable/machine-washable nylon bag to protect my bags from the elements (I'm a crazy TPFer). My favorite company is Baggu. The largest size fits my Selene and I put it in the Baggu and then feel much better about putting her on the ground
