Arriving from the Interdimensional Travel Agency, the Thermodynamics Flash t-shirt comes in a solid black cotton build with contrasting white, screen-printed graphics on the left chest and back. Portraying three schematic figures on the left chest, the shirt employs more scientific schematic designs in a larger print on the back for an educational look. The short sleeve is finished with a ribbed crew neck collar and a printed neck label for no-itch comfort.
