Abstract: A front panel for a sports bra has an interior liner layer having a back face contacting a wearer's skin, and an exterior shell layer having a back face facing a front face of the interior liner layer and coupled to the interior liner layer. A film layer is located between the front face of the interior liner layer and the back face of the exterior shell layer. The film layer becomes stiffer as a frequency of movement of a wearer's breasts increases, thereby absorbing forces caused by the movement of the wearer's breasts. A method for constructing a sports bra front panel with a thermally-induced shape memory polymer that exhibits viscoelastic properties when at body temperature and stiffens to absorb between about 0.015 N and about 0.03 N of force at frequencies of breast movement of between about 6 Hz and about 15 Hz is also disclosed.

Abstract: A front-close bra comprises a fabric back panel. A left inner bra cup and a right inner bra cup are coupled to the back panel. A left outer front panel is coupled to the left side of the back panel and is configured to cover the left inner bra cup. A right outer front panel is coupled to the right side of the back panel and is configured to cover the right inner bra cup. An inner closure couples a right side of the left inner bra cup to a left side of the right inner bra cup. An outer closure couples one of a right side of the left outer front panel and a left side of the right outer front panel to another area of the bra so as to hold the respective outer front panel in place over the respective inner bra cup that it covers.
