Period underwear is a sustainable and reliable alternative to other menstrual products. Highly absorbent, and made with moisture-wicking technology, fluxies period pants look the same as a standard pair of knickers but can hold up to 35ml of liquid.
When worn, period underwear is discreet, comfortable, and effective, so yes – they really do work!
No! Our leak-free period underwear can be a total replacement for disposable products, such as pads, tampons, liners and menstrual cups. Our period underwear range includes different levels of absorbencies for every kind of flow.
Our period pants can hold from between 1 tampon to 5 tampons’ worth of fluid – approximately 35ml of liquid.
For most flows, fluxies period pants can be worn all day or all night (up to 12 hours) before they need to be changed. If you need help deciding which styles you should start with, we recommend taking our Find Your Fluxies quiz.
Yes! Our period pants and leak-free undies are designed to completely replace disposable products whilst remaining leak free. Depending on which style of period underwear you choose, you can wear fluxies for between 8-12 hours, remaining leak-free. If your period pants feel damp, it's time to change to a fresh pair.
At fluxies, we create innovative period products using smart solutions, that help elevate your every day, through comfort, form, and function.
Our machine-washable and reusable leak-free period underwear provides a sustainable alternative to single-use disposable products.
Each pair of fluxies features an absorbent gusset area that keeps you dry, using our reliable built-in tech — this consists of a moisture-wicking top layer, a super absorbent middle layer, and a leak-proof bottom layer.
Designed in a range of absorbencies and styles, there's something to suit everyone.
You can find the details of each underwear style on our size chart, which is listed on every product page.
We recommend following the hip measurements to find the most accurate size (measuring your hips at their widest point).
Your new period underwear should fit snugly enough so that leaks cannot escape, but not so tight that it feels uncomfortable.
Caring for fluxies period underwear is easy! When you've finished wearing them, simply toss them in the wash with the rest of your clothes, then leave them to air dry.
Make sure you stay clear of fabric softener and bleach, as this can affect the absorbency of the underwear!
Top tip: our customers love air drying their period pants in the sun or on the radiator for super quick results!
