Frequently asked questions

Hygiene needs and facts

We asked our customers about menstruation:

"I feel fresh and confident thanks to the right products. I know that I don't want to unnecessarily burden the environment with waste, and I no longer have to suffer from the regular worries of buying hygiene products. More than 8 billion pads and tampons are thrown away every year, and I personally am happy , that I am contributing to the fact that these numbers are not even higher. With new products, my comfort comes first, also with regard to the environment."

A tampon takes 6 months to biodegrade, and pads and applicators sit in landfills for centuries!

We found that 30% of people with periods are willing to try products that are kinder to our nature. It's important to use whatever works best for you. If you want to contribute to reducing our planet's waste, try Bodylok reusable products.

How do panties work?

Bodylok is underwear that absorbs your period. Each pair is made with a patented design that wicks away moisture, controls odor, is super-absorbent and leak-proof. This means it will keep you fresh and dry. The products are ultra-thin for maximum comfort. Check out our How It Works page to learn more.

How much liquid can the panties hold?
  • Bodylok with medium absorption can hold up to 2 regular tampons in the amount of liquid (16-18 ml)
  • Bodylok with strong absorption can hold up to 4 regular tampons in the amount of liquid (33-36 ml).

Our absorption levels vary according to the style chosen. We recommend trying Bodylok panties for the first time at home to see how they work best for your body. It is important for every woman to understand that the density of fluid can be different. Therefore, the values ​​mentioned above are based on our tests, but they can sometimes differ.

Why do we manufacture goods in Asia?

The development and design of the product, the construction of cuts and all strategic activities necessary for the perfect functioning of the brand take place in the Czech Republic. The production takes place in China, in carefully selected factories, where through our quality manager we oversee precise procedures and adherence to a high standard, which makes us different from companies that only import Chinese goods. We chose Asian production because there is currently no one else on the market who can provide us with technology, materials and processing at such a high level in relation to the price than China. We regularly visit manufacturers and check the quality of production. We work exclusively with a family business that has 10 employees.

How do I choose the right underwear size?

Use our handy size chart to determine your hip and waist measurements.

How do I know what level of absorption to buy?

To find out which Bodylok briefs would suit you best. Consider how moderate/heavy your cycle will be throughout the week of your period. Below is an example:

For example:
During the heaviest days of your period, heavy period panties have the absorbency of the equivalent liquid value of 4 tampons. You can use it, for example, at night. For the days towards the end of your cycle, mid period panties can absorb up to the equivalent of 1 to 2 tampons worth of fluid.
Every woman is original in her own way and you need to approach your body individually.

How often to change panties?

This is very individual. It always depends on the strength of your period. Every woman has a different approach to wearing period underwear, and for most women it's their first time. Therefore, it is nonsense to convince you that the panties will last all day for up to 12 hours.

There is a group of women who wear panties for 6-8 hours. Some up to 12 hours. Other women have trouble changing panties when they are at work or traveling. This all needs to be thought through and tested first. As we recommend above, try our panties at home first and then see. If you are traveling or at work, we recommend buying a waterproof cover for used panties.

Are panties harmful to my body?

Absolutely no! We take the health and safety of our customers seriously. Therefore, all materials for Bodylok products are thoroughly tested by our supplier for harmful chemicals and independently certified. The materials meet and have GOTS certification, OEKO-TEX Standard 100 by OEKO-TEX®

How does the membrane regulate odor?

The NANOLOK layer, our technology, has an application of non-migratory silver commonly used in performance and medical devices to control odor and the spread of bacteria. "Non-migrating" means that it won't come off your underwear and that it only reacts to bacteria *on the fabric*, not on the skin (so your vaginal microbiome stays fresh and balanced!). You also need to choose according to the material.
