The endless white horizon. The otherworldly icebergs and glaciers. The kind of cold that makes you question all your life choices. (Does frostbite count as a souvenir?) Visit the edge of the world with limited-edition Antarctica shades. Black non-reflective lenses. Black and white Tidal G frames that float in water. Custom packaging with passport stickers. 4 out of 5 Emperor penguins approve. (The 5th one didn't show up due to krill coma.)
