The gears are labeled with philosophical phrases, 'I think,' 'therefore,' and 'I am,' creating a visual representation of the famous quote 'Cogito, ergo sum.' Made from a comfortable, likely cotton blend, this tee is ideal for those who appreciate intellectual humor and stylish design. Wear it casually, to lectures, or as a conversation starter. A cool and thought-provoking addition to your wardrobe.
