The open-wide, x-back strap system of the DynamIX bra were designed to make it easy to get on and off. The straps are padded and strategically positioned for extra support. Double-layered and pre-formed cups give you a supportive and seamless bra. This bra was made with high intensity and maximum support in mind. If you're a runner, a rider or a jumper, this award winning bra was made for you.
