The Zoot Women's Performance Tri Team Racerback Tank Top works great as a race day top, thanks to its quick drying fabric with four way stretch. Designed as a racerback tank for full range of motion, this top won't hold you back when you're swimming, riding, and running. Its built in bra provides extra support, while the longer drop tail hem enhances its fit for cycling. Featuring an Italian polyester spandex blend, this jersey offers the benefits of compression and muscle support. It's rated at UPF 50, meaning it'll protect you from the UV radiation on bright summer days. Moreover, you'll find Zoot's proprietary Seamlink, which lowers the stitching profile for a smooth, non irritating feel.
