The O2 Performance Tank

Run your course. A running tank so weightless, you’ll forget you’re wearing it thanks to ultra-light mesh fabric that doesn’t hold sweat.

A light-as-air mesh that won't weigh you down on your runs. Made to sit off the skin, it’ll keep you fresh thanks to breathable, sweat-wicking, and anti-stink tech.
