Don’t let the lace fool you, this shirt is a beast. The secret is in our HeatGear® Sonic fabric. A reinvention of our original HeatGear®, HeatGear® Sonic is softer, lighter, and more breathable than ever. That means you can go as hard as you want without ever feeling held back. We also replaced the full back panel with a gorgeous performance lace for even more breathability and bold style.
