This blue and red design features a hollow square inside of a circle. A nearly identical shirt was worn by David Haller (Dan Stevens) during Season 1 Episode 2 of Legion. The t-shirt is also available in long sleeve like David wears on the show. Not many people know that each episode's theme is reflected in his shirt. For example, the hollow square in the circle symbolizes David's missing memories that they were trying to piece together in the episode.
