The Experiment Under Armour Tee
When the cork blew, XIII didn’t stay in the flask.
This Under Armour tee carries the full Specimen XIII containment breach mark — lab flask tipped, biohazard seals broken, neon toxin pouring into Roman XIII. Built for heat, motion, and long sessions: UA performance fabric that wicks, stretches, and stays light when the experiment runs hot.
Wear the breach. Fund the work. The experiment is still in progress.
