Leak-Proof Underwear FAQs

How do leak-proof panties work?

Proof® leak-proof 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 leak-proof 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. 

Leak-proof 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 leak-proof panty combined with their nursing bras to take care of their children in comfort.

Can Soma’s Proof® underwear work as period underwear?

Yes, Proof® panties can be worn as period underwear. When shopping for leak-proof underwear for women, you’ll want to consider the absorbency levels of each style. Our leak-proof panties range from super-light to super-heavy absorbency. 

Do Proof® leak-proof underwear come in different styles?

Yes, Proof® leak-proof 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 leak-proof 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 leak-proof 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 leak-proof underwear comfortable?

Yes, Proof® leak-proof 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. 

Our leak-proof underwear for women are designed to be breathable, soft, and moisture-wicking for optimal wear. You can expect all-day and night comfort when you wear a pair of our leak-proof 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 leak-proof panty the most.
