I have an OG BOGG bag from like 5 years ago, the big one. I do like it, but I only use it locally.
I do not take it with me on an airplane, its heavy and a pain in the butt. If I'm driving somewhere, I love it. I like it at the beach/pool mostly, but again, I don't want to attempt to fly with it. Mine is so big it probably wouldn't fit under a seat anyways. I didn't really think about that part when I bought it.
I also feel like the lack of any built in storage is annoying. So I do have to use a lot of pouches/clip on pieces for it that pop off constantly. I'd give it like a 6/10 for me in overall love.
