Modibodi
Australian leak-proof underwear for periods, sweat, and everything in between
The Marathon Runner Who Built a $140 Million Underwear Empire
Modibodi was founded in 2013 by Kristy Chong, an Australian mother of four whose eureka moment came during marathon training when she experienced stress incontinence — and realized the only solutions available were ugly, uncomfortable disposable pads designed with zero regard for the women wearing them. Chong spent $20,000 of her own money on research, consulting with chemical textile engineers and testing fabrics from around the world before developing the patented absorbent technology that would become Modibodi's foundation. The brand grew from 500 initial garments to a company valued at AU$140 million when Swedish health giant Essity acquired it in 2022. Chong received an Order of Australia Medal in 2023 for her contribution to business and women's health.
What Makes Modibodi Different
Modibodi's patented Modifier Technology uses a three-layer system: a top layer that wicks moisture, a middle layer that absorbs and locks in fluid, and a bottom layer that provides leak-proof protection. Unlike some competitors that focus exclusively on periods, Modibodi addresses the full spectrum of leaks — periods, bladder leaks, sweat, and postpartum bleeding — making it a more versatile product for a wider range of life stages. The technology is rigorously tested: each pair can absorb between one and ten tampons' worth of fluid depending on the style and absorbency level.
Key Product Lines
Period Underwear covers the core range across all silhouettes and absorbency levels. Active Leak-Proof brings the technology into workout-appropriate styles with moisture-wicking performance fabrics. Maternity serves pregnant and postpartum women. Swim features leak-proof swimwear for periods at the pool or beach. Incontinence styles address light bladder leaks with discretion and dignity. The brand also offers a Teen range and a Men's line for bladder leaks.
Who Modibodi Is Best For
Modibodi serves an exceptionally broad audience: menstruating women seeking reusable alternatives to disposable products, new mothers dealing with postpartum bleeding, active women who experience sweat or stress incontinence during exercise, and anyone managing light bladder leaks. The Australian brand's broader approach to "leak-proof" — beyond just periods — makes it relevant to a wider range of customers than period-only competitors.
Price and Sizing
Underwear from $18 to $42, swimwear from $35 to $75, activewear from $30 to $55. Sizes from XS through 5XL, making it one of the most size-inclusive options in the leak-proof underwear space.
