When you need to get ready in a hurry and you can't find your sport bra, slip on the Oakley Women's Energy Tank Top. This silky tank top has built in bra that minimize the bounce with an easy going air. O Hydrolix fabric blends polyester and elastane to reduce the body chilling effects of drying sweat. Drop armholes give you freedom to move as you please, be it cranking out sets of pull ups or throwing down on a rowing machine. A band at the bottom keeps the tank in place if you happen to find yourself upside down. Odor causing bugs will have to find a new place to live, since this tank says you're not welcome here. While smaller busted women will have no issue with inner shelf bra containing their chest when doing jump lunges, more amply endowed ladies may want to keep things on the tame side if wearing the Energy top without other support.
