Frequently Asked Questions (FAQs)

What are Leakproof Panties?

Although their appearance is the same as a normal panty, the difference lies in the special fabric they are made of, as this allows the absorption of menstrual flow without being transferred to your clothes. 


In addition, they are antibacterial to avoid odors and keep you dry. 

The best thing is that they can be washed after each use, so you can reuse them.

How do I wash and dry Leakproof Panties?

Wash them before the first use with cold water (preferably in the washing machine). This helps to improve their absorbency.


After each use: First rinse or soak them in cold water. You can wash them by hand or in the washing machine. It is very important to wash them in cold water, without softener, without Marseille soaps and without bleach. Never dry clean them. The sun is the healthiest way to dry them!

How to wash the panties?

Hand washing and air drying are the perfect options. You can also machine-wash them, but only on gentle or soft settings because of the sensitive material under the waterproof lining. Please note that putting the panties in the dryer may cause damage to the waterproof lining and cause them to shrink.

What size do I need?

Follow the size guide provided on each of the product pages.

How absorbent are the Leakproof Panties?

They absorb up to 4 times worth of disposable pads or 15 - 25 mL.

How long can I wear Leakproof Panties?

It depends on each style and your menstrual cycle or flow or incontinence. Only you can find out exactly how long they will last for your specific case. But they can last up to 8 hours.

Do the Leakproof Panties smell bad after use?

Not at all, unlike disposable pads, Leakproof Panties are free of chemicals, so you will not notice the odor that is produced by mixing blood with the chemicals in disposable pads.

How many Leakproof Panties do I need?

It will depend on your use and your cycle, but as a guideline we recommend you have at least 3 or 4 to change during your cycle. To have a full Leakproof Panty cycle, we suggest around 10-14 Leakproof Panties.

How long do Leakproof Panties last?

Leakproof Panties have the same lifespan as regular panties. Their average lifespan is 3 to 5 years, depending on use and care. There are customers who wear them all the time, whether for urinary incontinence, vaginal discharge or just for menstruation. Therefore, depending on the use, like any other garment, will depend on its useful life.

Will I feel wet if I wear Leakproof Panties?

Not at all, the top layer of thin cotton allows blood/urine to drain and be absorbed and stored in the next layer. This way the vulva is not in contact with the blood and the cotton layer stays soft and dry.

Do I need to use a tampon or pad when I use the Leakproof Panties?

No, Leakproof Panties are designed to completely replace disposable tampons and pads. However, if you have a very heavy flow or feel more comfortable, you can use our Reusable Pads with them!

Can Leakproof Panties be used in the sea?

Normally Leakproof Panties are not designed to be used in the water. However, several customers have reported using them in the sea or lake without any problem. We advise against using them in the swimming pool.

Can Leakproof Panties be used for sports?

Yes, many customers have tried them and have received positive comments about it. We recommend trying them first and, once you feel comfortable, try your favorite sporting activity with them.

Can they be used for urinary incontinence?

Yes, they can be used for urinary incontinence.

Can they be used postpartum?

Exactly, Leakproof Panties can be used for menstruation, light to moderate urinary incontinence and postpartum.

Does the absorbent area extend far enough in the front & back of the panties?

Yes, the back absorbent area extends to the top of the buttocks (up to the end of Leakproof Panties) and the front covers the entire pubic area.
