"I'm completely sold on the period panties. I'm never going back to tampons!"

  • It’s science, period. Our period-proof underwear absorbs menstruation blood, prevents leaks, controls odour and wicks moisture. The secret is Engineered Leak Tech™ - patented three-layer technology with built-in protection placed in the gusset of the underwear.

  • Our period-proof underwear is tested extensively and lasts for up to ten hours of wear.

    All of our models have the capacity to hold a large amount of menstrual blood. The High period-proof panty can hold up to 40 ml of blood - which is quite a lot, since the total menstrual fluid loss per period is on average 35 ml.

    But each body is unique, so the most important thing is that you choose the absorbency level that matches your personal flow level.

  • Our period-proof underwear is washable and can be used again. And again. We recommend starting with 3-5 pairs: that way, you’re covered for an entire menstruation cycle without having to do too much laundry. But every person is unique, with individual flow levels and laundry facilities. So, you can always start with 1-2 pairs to complement your usual protection. That‘s a good way to ease into using a new product - and to find out what works best for you.

  • We recommend you go for the same size as you usually choose. Our period-proof panties are designed to feel snug at first, and then relax with washing and repeated wear for that perfect fit.

    See our size guide here.

    To make sure that you find your perfect fit, our underwear comes in a wide range of sizes.

    Women: XS, S, M, L, XL, 2XL, 3XL.

    Teens: 134/140, 146/152, 158/164, 170.

  • We design period-proof underwear for all levels of bleeding, from light to heavy periods. The highest absorbency level is called Super and can hold up to 50 ml, which is equivalent to 5 tampons or pads. Heavier bleeding than that is unusual, but we’re all different. And that’s just how it should be.

    If you are worried about bleeding more, we recommend that you start by wearing your period underwear at home during a heavy day. That will put the underwear to the test - and put you at ease while you figure out how it works.

  • Being female should be hassle-free. That’s why we offer a free trial for 45 days when you buy our period underwear for the first time. Just contact our customer service, tell us about your reasons for wanting to return the product, and we’ll refund you - just like that.

    Please note that the trial warranty only applies when you try a product for the first time.
