Squats. Burpees. Double unders. You power through them all. Make the most of your efforts in this tank that's made to move. The back's shorter hem length creates a back-to-front drop for easier movement, and the racerback construction allows your arms more range for a set of snatches. Lightweight fabric keeps the fit breezy, but don't let it fool you. It's durable enough to handle the whiteboard's orders. We packed this tank with extra cooling technology to bring the heat down a notch. ACTIVCHILL fabric maximizes breathability for a chill feel, while Speedwick works hard to oust sweat.
