With PureMove Bra, Reebok unveils a technologically advanced sports bra that uniquely responds and adapts to movement to provide women with a customized amount of control and support. It uses the brand’s new proprietary Motion Sense Technology, which is the result of treating a performance-based fabric with ‘Sheer Thickening Fluid’, a gel-like solution that takes a liquid form when in a still or slow-moving state and stiffens and solidifies when moving at higher velocities.
