They used to call people who reached 40 over the hill, but we’re not so sure that’s true anymore. 40 is the new 30 these days: 40-year-olds are still active and have plenty of fun.

You can share the joy (or dread) of reaching that milestone with a hilarious 40 years old T-shirt. Our selection features a wide variety of messages and statements, from proud to not-so-much. We features shirts that tie the 40th birthday with a number of other hobbies and interests such as music, video gaming and cars.

Our shirts come in a variety of styles and colors, so you’re sure to find something they’ll love. We print our designs on 100% cotton or poly-cotton blends, so they’ll feel soft and well-worn from day one, but last for months and months of washings and wearing’s.
