From Vuori Website: The perfect addition for all your outdoor looks, the Pose Plyo Tank has all the performance details you need and more—like moisture-wicking stretch rib fabric and UPF 30+ sun coverage. It even has a full-support bra built-in and a honeycomb mesh lining. Great for travel, a quick morning workout, or just running errands on the weekend. I wore for a summer and decided I didn’t like the built in bra feature so I am selling. Size large but could comfortably fit a medium sized person.
