I finally took a pic. It's weighed down with my stuff in it. The LB pics make it look better, mine is kind of like a garbage bag..lol. It is very comfy and squishy though.
I like it! It seems to depend on what I'm wearing, but sometimes the strap does slide off. The bag is kind of 'slick'. The weight from the accesories might make it prone to slipping too, but most of the time it stays put.
