Period-proof underwear - Sleep

Period-proof your sleep with this highly absorbent style, enforced with an extended gusset for extra front-to-back coverage. This oh-so-stretchy pair will stay in place and keep you safe, dry, and protected. All night (and day) long.

"For the first time in years, I slept through the night without worrying about leaks or the pad sliding away."

  • Our period-proof panties are designed to keep your periods and sneeze leaks safe. But unlike disposable period products such as tampons and pads, you wear period panties again and again. Just like your regular underwear. A win for you, and for Mother Nature.

  • Yes, very much so. Regular period-proof underwear will most likely do the job perfectly well during the night. But, depending on your flow level and sleeping position (some of us just can’t keep still, right?) you might need a little extra protection when sleeping. And that's why we created night panties, that come in two different silhouettes:

    - Engineered Boxer Super Period Proof

    - Engineered High Waist Super Period Proof

    The unique thing about our night underwear is the length of the gusset – it guarantees safety when you sleep. It doesn’t matter if you sleep on your back or snooze on your stomach (or maybe both?). The blood will stay exactly where it should, all night. Sweet dreams!

  • Our period-proof underwear is designed to keep you comfy and dry with an innovative built-in protection in the gusset - the patented Engineered Leak Tech™. It’s a completely leak-proof solution with three layers:

    1. A wicking layer that efficiently transports the blood to the absorbent layer and keeps the surface in contact with the body dry.

    2. An absorbent layer that holds the blood securely and undetectably, with an anti-odour and antimicrobial treatment.

    3. And finally, a barrier layer that prevents any leakage of body fluids, while still being breathable.

    In addition, our period underwear has a perfected fit that lets the Engineered Leak Tech™ work its magic. The fit hugs your body, securing the position of the underwear and making sure that the gusset stays in its place.

  • 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.

  • 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.
