Zoot's Performance Tri Racerback Women's Jersey provides the same features found in the Performance Tri Tank, but in a slightly more supportive racerback package that might leave you with more tan lines, but will also help you stay comfortable and focused when you're on the move. The Performance Tri Racerback was constructed from Performance Endura fabric, which is soft to the touch, dries quickly, and wicks sweat away during the bike and run. At the back, the classic racerback shape provides unlimited mobility, clean lines, and support, while mesh insets help increase breathability and cooling. A built in bra provides support and is lined with breathable Power Mesh to increase comfort, while Zoot's SeamLink technology nearly eliminates seams to reduce irritation and discomfort. Reflective details, UPF 50 sun protection, and dual side pockets complete the setup, so you'll be safe, well fed, and comfortable during training runs and races.
