FAQs
Period underwear looks and feels like regular underwear, but it’s built with multiple absorbent layers that soak up menstrual flow while keeping you dry and leak-free. Fri Period underwear uses a breathable, multi-layer system designed to absorb period blood, lock in moisture, and prevent leaks - without feeling bulky or diaper-like. We think it's by far the comfiest way to manage your period!
Yes. Fri Period underwear is designed to be worn on its own for light to heavy flow days, depending on the style and absorbency level you choose.
Some also wear them as backup with a cup or tampon for extra peace of mind.
A lot of people choose to wear them in between their period as well so they don't get caught out by suprise leaks.

Check the product description on each style to choose the best option for your flow.
Yes. Fri Period underwear is made without using PFAS or other harmful chemical treatments. The fabrics are OEKO-TEX Standard 100 certified, which is a giant tick of approval for the safety of the product. The layer closest to your skin is soft, breathable organic cotton, so it's suitable for even the most sensitive skin.
Our materials are tested for safety and skin comfort.
PFAS are “forever chemicals” often used in waterproof fabrics. They have been linked with all sorts of issues, including hormonal irregularities and even cancer. Because period underwear sits against one of the most absorbent areas of your body, choosing PFAS-free options helps reduce unnecessary exposure to chemicals - especially during your period.
Absolutely. Fri Period underwear is designed with sensitive bodies in mind. The organic cotton gusset is breathable, gentle, and free from harsh treatments, making it suitable for even the most sensitive skin and those experiencing their first periods.
Period underwear should fit snugly but comfortably - ike your favorite everyday underwear. It shouldn’t dig in, bunch up, or feel loose around the legs, as a good "seal" helps prevent leaks.
Use the Fri Period size guide and measure your hips for the most accurate fit. If you’re between sizes or prefer a more relaxed feel, we recommend sizing up.

After wearing, rinse in cold water until it runs clear. Then machine wash cold with your regular laundry and air dry. Avoid fabric softener, bleach, and heat - they reduce absorbency and your Fri Period undies won't hold their shape as long.
With proper care, Fri Period underwear can last 2–3 years or more, making it a reusable, eco-friendly and low-waste alternative to disposable period products.
Some staining over time is normal, but Fri Period designs include thoughtful features like our adorable printed gusset design to help minimize visible staining. Rinsing soon after wear helps keep them fresh, too!
