US Patent 8128457 Athletic bra

A seamless athletic bra includes different regions with different levels of support. The bra is formed from layers of material adhered together. Altering the types of materials comprising the layers in a region changes the level of support in that region as compared with other regions of the bra. A first region having the lowest level of support is found in a back panel and in the molded cups. A second region having a medium level of support is found in the front portion of the strap. A third region having a high level of support is found in a framework that follows the contours of the molded cups and in a back portion of the strap.
