2019's LibrePlanet shirt comes in purple, high-quality cotton. The design imagines this year’s theme, “Trailblazing Free Software,” as a space journey to unexplored frontiers, featuring a cute little spaceship zooming out of a wormhole filled with eerie green planetoids. These are the fitted sizes.
