Why healthy underwear? image

Why healthy underwear?

Wearing the wrong underwear drastically increases your chances of having a vaginal infection or irritation!

- 80% of all females experience vaginal irritation
- 75% of females even experience vaginal infections at least once in their life
- 63% of females often wear a pantyliner to deal with the discomforts, which triggers extra irritation

That’s why we made underwear that:

▪ Significantly lowers your chances of irritation
▪ Takes care of the discomforts you might experience
▪ Is made out of eco-friendly fabric while at the same time gets rid of a bunch of single use pantyliners
▪ Actually makes you feel & look good!
