Sizing and Washing Tips
This is a classic. Call it what you will: the Devil's Triangle, the Impossible Triangle, the Penrose Triangle. They are all the same trick of a few lines and quite impossible in our mundane three-dimensional space. Though not real, it originated with a real Swedish guy named Oscar Reutersvard in 1934. Although a casual glance sees it as perfectly legit, closer inspection leads to a frisson of cognitive dissonance. Enjoy the basic model or our more elaborate, Magritte-inspired impossible window on the sky. Why not get both!

The men's relaxed fit t-shirts run small, so please order one size larger than your usual. The other styles run true to size. We wish we could bring you samples, but we’re waiting for improvements to current teleportation technology.
  • The men's relaxed fit tee is a heavier cotton with a looser fit. They run small, so order one size larger than usual.
  • The men's trim fit tee is more fitted and a medium weight ring spun cotton. We print up to 4XL in this style!
  • The women's v-neck is a medium ring spun cotton with short sleeves.
  • Youth shirts are suitable for both boys and girls in a heavy ring spun cotton.
  • We recommend machine washing in cold water with the shirt inside out; tumble dry on low or medium. If you iron (wow!), we recommend turning the shirt inside out first.
