Love this bag! I've never seen it in person, but depending on your outfit, it can work in any situation IMO.
I have a mesh defender cover I use as a bag most if the time, and I LOVE the look, weight, and function. It's very flexible too. I think the bag you're thinking about has a similar vibe, but I feel like anything plastic will be a little stiff. It's really cool though, and I considered getting it, but I think it's too similar to what I have.
Here's one way I used mine. I also used it by itself, but I can't find the pics right now. I'll find and post later if you'd like.
