I've flown with it once a few years ago. I either wore or hand carried it through the airports. It would take up a lot of room in a bag. But if you're wandering around town or have something you can tie it to the outside of, it's great. I have tied it to the outside of my pack and that's worked well.

Being that I got it from Target, there's some issues with the buttons after a few years. But that's not hard to fix. Once/if it dies, I'd either get another one or similar style. Mines the bridge coat variant (comes down to the thigh instead of the waist).

Do you intend to do anything like technical hiking or working in it? I've got a pea coat that I enjoy using around 35 degrees Fahrenheit.

It's a heavy wool coat that's pretty weather resistant and warm. And it'll last forever.
