Sizing and Washing Tips
By now we've all seen the famous British poster exhorting us to Keep Calm and Carry On. Apparently eminent physicist Max Planck did too, and he wrote his own geeky version aimed at his fellow scientists (we're not kidding, for once). The wording is a little stiff, and very much spoken like a sensible, straightforward kind of thinker, he wants us to continue working. Wear it to a picnic! Wear it to the moon! The circumstances of the slogan's creation are not amusing, but maybe we can wear it (literally) a bit more lightly now.

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.
