Yes! THATDAY has a special multi-layer system that soaks up menstrual blood in a hygienic way and traps it there so it can’t come back out unless you wash it. It works similar to how a single-use pad would, but with less bulkiness and more areas for absorbency. You can use them for heavy periods or to protect yourself from spotting.

Our period proof underwear is made to be worn up to time until it feels comfortable to you. There is no risk of leaks thanks to our absorbent lining of 3 layers doubled with a waterproof fabric that retains liquids. If, however, your flow is heavy and you think you might have leaks, you can also use classic sanitary protections in addition, but it’s not mandatory. The ideal is to see for yourself and test our menstrual lingerie in the comfort of your own home, pj’s (and the cake, of course) of one day of your heavy flow.

A great way to give period underwear a try is to wear it overnight towards the end of your period when your flow is lighter. This way you can start experimenting and feeling the benefits even at the end of your cycle! Then additionally, trying it out as a backup on a heavier day is great too!

Mostly like a regular pair of panties, it’s thicker than your average pair of underwear, but is not obvious under tight pants.They feel a little bit like bathing suit bottoms, but the inside is soft like normal underwear.

With one pair it will be enough to understand how they work and do you like this solution. However, to feel comfortable and relaxed through out the day and night you will most probably need 2-3 pairs or more depending on the length of your period.

The answer is – YES, of course you can! But for your security and calmness we recommend experimenting them at home at your first period day and night to find out how it works for you. How often you should replace them, and how comfortable you are with THATDAY reusable panties.

Да, и мы даже рекомендуем это сделать! Однако учти, что трусики можно обменять на другой размер или модель только в том случае, если они не были в носке и все гигиенические наклейки сохранены. 40-дневный пробный период не действует, если после использования окажется, что размер слишком маленький.
