Sport Period Pants: Frequently Asked Questions
-
Yes — our collection of sports period pants are the ideal option for managing your period whilst exercising. The highly absorbent design gives you all-round support, without the risk of leaks or movement that some other period products may have.
Period pants are an excellent choice for athletes who may not enjoy internal use period products like tampons or menstrual cups, but are tired of sanitary pads or pantyliners moving or feeling uncomfortable during exercise. Period pants are a safe and secure option, which can free you from discomfort and allow you to focus completely on your workout.
-
We recommend changing our period pants once every 8 to 12 hours (depending on your flow, the style, and the absorbency you’ve opted for). However, with our sports period pants, we recommend changing them once your workout is finished, just as you would with your standard gym clothes. Easy to care for, you can throw them straight in the wash, or give them a quick rinse and squeeze in cold water first if you wish.
-
Sports period pants are a great choice for runners — even long-distance runners, as there’s no need to stop partway through your run to change them, as you may have with other period products like disposable pads or tampons. Any of the options from our sports range will be suitable. However, many of our customers enjoy the long leg design of our period boxer shorts, which helps them to feel extra secure, and even helps to avoid chafing on the upper thigh. Whatever the activity, we have the perfect pair of sports period pants to give you confidence!

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.
-
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.
When worn, period underwear is discreet, comfortable, and effective, so yes – they really do work!
-
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!
