You’d be forgiven for thinking this festive headgear has a pair of elf ears on the side. But look closer and you’ll find the Star Trek Spock Santa Hat has far geekier origins. Highly illogical (sorry, couldn’t help it) but thoroughly different, this science-officer-blue hat even has a mini Federation insignia on the fluffy white rim.
Practical head-warming properties aside, we can confidently say that no self-respecting Vulcan (half-human or otherwise) would be seen in the same solar system as a bit of Christmas kitsch like this. But that’s fine. All the more for us. And besides, Starfleet officers with red hats always get killed anyway.
