The accidental invention that revolutionized women's sports: sewing two jockstraps together.
In short: Before 1977, women struggled with chafing and runaway straps while exercising. The solution arrived when two women, frustrated by their ordinary bras, sewed two jockstraps together in a university costume shop. This humble prototype, the jockbra, sparked a revolution in comfort and confidence that changed athletics forever.
The sports bra emerged from a genuine need for functional athletic wear. In 1977, Lisa Lindahl and theater costume designer Polly Smith, assisted by Hinda Schreiber, sought a better alternative to standard bras. Working in the Royall Tyler Theatre costume shop at the University of Vermont, they created the jockbra. This invention was later renamed the Jogbra and eventually led to the trio's induction into the US National Inventors Hall of Fame in 2022. While Glamorise Foundations, Inc. had introduced the Free Swing Tennis Bra in 1975, the Jogbra is widely recognized for its impact on the industry.
The mechanics of the sports bra focus on minimizing breast movement, which can cause pain for about a quarter of women athletes. Designs generally fall into two categories: encapsulation, which uses molded cups to support each breast individually, and compression, which holds breasts firmly against the body. Research by Joanna Wakefield-Scurr has shown that an ill-fitting bra can even shorten an athlete's stride by 4 centimetres. These garments are now highly specialized; for instance, competitive shooters may use specific designs to prevent contact with their firearms, while rowers require different support than runners due to varying impact levels.
The cultural significance of the garment was cemented in 1999 when Brandi Chastain celebrated a victory at the FIFA Women's World Cup by removing her jersey, revealing her sports bra to the world. This moment transformed the item from a hidden piece of equipment into an iconic symbol of female athleticism. Today, the technology continues to evolve, incorporating materials like Lycra to manage perspiration and specialized structures to accommodate high-intensity movement. Despite concerns that these bras might restrict breathing, research indicates that while they exert pressure on the rib cage, they do not significantly impair respiratory function.
