Simplicity is a beautiful thing. We made this bra because we wanted a seasonless classic that we could wear under any tank, for every activity. We gave it a COOLMAX liner and added mesh in strategic places so we can blow off steam when we work up a sweat. Key features the racerback design means this bra is invisible under most athletic tanks thin straps allow you to move and twist with ease mesh panelling between the cups and on the back helps sweat evaporate quickly chafe-resistant elastic band under the bust provides support where you need it most Tech specs designed for: yoga, run, cycling fabric(s): luon®, mesh, COOLMAX® properties: chafe-resistant, breathable, preshrunk, four-way stretch, moisture-wicking support level: medium coverage: medium Good preowned condition.
