A cuffed beanie, or toque, with a formula of symbolic propositional logic exemplifying the law of the excluded middle.
In English, the symbols read as, for some proposition P, "either P or not-P". It's similar to saying that any claim is either true, or its negation is true. An axiom of classical logic, some other systems of logic do not require this.
The hat is snug and form-fitting, to keep you warm in the winter.
100% Turbo Acrylic
12" in length
Hypoallergenic
Unisex style
