I bought the Bucky. It's nice. Hard not to make jokes about an "eye bra".

If you sleep on your back, or don't have a lay flat bed on a flight, and your primary concern is free space for your eyelids to flutter unobstructed, then the Bucky is what you want.

Otherwise, I still prefer the Alaska Bear mask over anything else I've tried. (I'm a side or stomach sleeper.)
