Abstract: A support brassiere for the female breasts for use in energetic activities such as running, jogging, aerobics and track events. A pair of flexible cups are supported from above by shoulder straps, and beneath by an encircling band. An inelastic flexible stabilizer strip is attached to the encircling band and is adjustably brought to bear against it and the rib cage immediately below the breasts. The support from below prevents breast sag and thereby reduces the bouncing of the breasts.
