Leakproof Panties FAQs

How do leakproof panties work?

Proof® leakproof women's underwear has a patented Leak-Loc core that's capable of holding up to eight teaspoons of liquid while minimizing odor. These panties feature a liner that covers from front to back and is capable of preventing overflow from escaping.

Our leakproof panty can be used with or without additional protection and is designed to be worn to cover a number of situations that might arise. Proof® panties are capable of catching bladder leaks, heavy period flows, and discharge. They're also recommended for pre- and post-partum wear.

Leakproof panties are designed to provide discreet protection from light to heavy discharge. You can depend on them for protection, whether you wear them at work or during vigorous exercise.

They're also great for mothers who need to wear a leakproof panty combined with their nursing bras to take care of their children in comfort.

Do Proof® come in different styles?

Yes, Proof® leakproof panties come in different styles and cuts that meet your need for no visible panty lines under all types of garments and protection from leaks.

The high-waisted brief from our vanishing underwear line comes up to your natural waistline to provide full coverage when you need it the most and offers no-show, no-roll wear. Pick the bikini style for its high-cut leg and form-fitting front and back.

Each leakproof underwear design features a specific level of absorbency. As we mentioned, Proof® panties can hold up to eight teaspoons of liquid; how much they can hold depends on the specific panty's absorbency level. This can range from super-light to heavy.

With heavy absorbency, the bikini cut works best for exercising or sleeping, while the high-waisted leakproof underwear has moderate absorbency and is designed to handle bladder leaks and periods or to replace tampons, pads, or a cup. This high-waisted style also acts as shapewear by providing mild compression that draws in your stomach while alleviating cramps and bloating.

Is leakproof underwear comfortable?

Yes, Proof® leakproof women's underwear is comfortable. The outside of the underwear is made from the same material that our other panties and thongs are made from, and the lining features soft yet absorbent materials that won't scratch.

You can expect all-day and night comfort when you wear a pair of our leakproof underwear. To ensure comfort and coverage when you need it, get our panty packs in your favorite style so you won't be without when you need a leakproof panty the most.
