Proof, a female empowerment company, has launched its new line of leak-proof, period-proof, worry-free undies. This new venture from the founders and sister-preneurs of Belly Bandit, a recognized leader in the maternity industry, delivers meticulously designed and expertly constructed leak-proof undies for women.

This premier range of functional intimates, designed by three sisters utilizes their patented leak-loc technology to ensure reliability. Proof is the first leak-proof underwear that is really (really) leak-proof.

Through years of development and comparison tests, proof has consistently outperformed its competitors. The leak-loc technology combines ultra-light and breathable layers of leak-proofing plus leak-loc edges to ensure fluids can’t escape. Vital antimicrobial fibers and innovative absorbent and moisture-wicking liners trap in moisture, keeping women dry and comfortable. The clever designs and no-show fit, give proof undies an edge in both style and peace of mind, the company says.

The first collection of proof includes five absorbency levels from super-light to super-heavy. For example, the Everyday Undie handles life’s little leaks and holds half of a regular tampon or teaspoon of liquid. The Hipster Panty can hold up to five tampons or ten teaspoons of liquid, the most fluid absorption out of any underwear on the market.

From managing a period, pregnancy, or new-mom life, to dealing with sprinkles or sweat, women can rely on the security of proof to provide a dry, safe and eco- friendly feminine hygiene solution. More affordable and earth-friendly than traditional pads and tampons, which can take up to 500 years to decompose, proof undies can relieve the need for sanitary pads, making it an excellent solution for women and the environment.

The debut line of proof is available for purchase exclusively at shopproof.com and on bellybandit.com. The underwear comes in sizes XS-XL and includes seven silhouettes in both black and sand colors, with prices ranging from $25-$43 USD.
