Red Vector Tee

Appearance
The Red Vector Tee is a dark red, short-sleeved shirt with four parallel rows of white arrows that alternate direction, hence the name. At the bottom is a tiny, light blue tag with the logo in black, with another in white below the nape.

Trivia

 * The design on the shirt is a mild optical illusion similar to the café wall illusion, in that the rows can appear to be slightly angled despite being completely parallel.
