Going Batty (Black) Men's Crew socks
These socks aren't upside down, but the bat on them is! Bat Fun facts-most Bats sleep hanging upside down because they are mammals and can’t take off into the air like light-boned birds can (at least not without difficulty). But, if they're hanging, all they do is let go...and fly. Bats are the only animals that spend most of their time hanging upside down-feeding, raising their young, and, yes, sleeping or roosting this way. Cool realistic looking bats roost on these black socks. Contents: 55% cotton, 43% nylon, 2% spandex. Fits men's shoe size 7-12.5, Women's shoe size 8.5-14.
