The Triaction Control Lite sports bra features a dynamic LITE concept that delivers extreme support without the bulk. Triumph's 3D Powertech Innovatio n is 3 layers of anti-bounce control and smart 3D power straps, which are lightly padded for low friction performance; all the comfort without the bulk. This underwired minimiser bra delivers comfort and compression, and has been bounce tested by the University of Portsmouth, with outstanding results of 74% bounce control giving extreme support. The extra large underbust band doesn't dig in and breathable cups ensure a dry workout every time. This sports bra is also made with anti bacterial, soft fabrics and tested for sensitive skin. Material: 81% PA, 19% EL. boobydoo says: Triaction's new range is designed to help us look and feel good at the gym, with great prints, shapes and support levels. We love the multi-optional straps that can make this sports bra racer back and its super light design makes it really comfortable.
