Penguins are good at staying warm when it's chilly out. They have thick skin and lots of blubber, plus they're notorious for cuddling with their buddies. These fun penguin socks are perfect for cuddling, too, if your toes get cold. Plus, these penguins have scarves and hats. Not a bad idea. Add a scarf to your PJs, light up the fireplace, and get to snuggling!
