When it's not broken, there's no need to fix it. That's just what Under Armour has done with the Tech 2.0 Fast Tank. Fast and furious, this classic tank is part of the original go-to training gear and hits the three essentials: loose, light, and cool for a distraction-free run. Moisture-wicking and quick-drying fabric ensure you stay dry, while the anti-odor technology fights against odors to help keep lasting freshness as you work up a sweat.
