5 Reasons Period Panties Are Not on the Naughty List

🎄 ‘Tis the season to be picky about what touches your skin — especially when it comes to your most sensitive areas. If you’re looking for period panties without PFAS, we’ve got good news: the right pair is safe, sustainable, and anything but naughty.

At Fri Period, we believe period care should never come with a side of chemicals. So we’re breaking down why our period underwear is officially on Santa’s Nice List.

1. They’re made without PFAS 

Let’s start with the big one. PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals found in everything from waterproof coats to non-stick pans — and yes, unfortunately, in some brands of period products too.

These so-called “forever chemicals” don’t break down easily, and when absorbed through the skin, they can linger in the body for years. Studies have linked them to hormonal disruption, reproductive harm, and more. That’s not exactly the kind of surprise you want in your menstrual underwear.

That’s why Fri Period proudly offers period panties made without PFAS — full stop. No greenwashing, no vague language, just transparency and safety.

Now it's worth noting that, because PFAS leach into our environment (yup, our soil and our water sources too!), it's impossible to avoid them entirely but we do what we can to limit exposure. Every little bit helps!

2. They’re Made With Organic, Skin-Loving Materials

PFAS aren’t the only thing we skip. At Fri Period, we say a hard no to harsh synthetics, endocrine disruptors, and mystery fabrics.

Instead, we use:

• Organic cotton that’s soft, breathable, and free of pesticides
• Oeko-Tex Certified and OEKO-TEX STANDARD 100 fabrics tested for over 100 harmful substances
• Bamboo blends and moisture-wicking fabric that feels luxe on skin

Whether you have sensitive skin, allergies, or just don’t want chemicals anywhere near your vulva (valid), our undies are made to be gentle and effective.

3. They’re Leakproof Without the Plastic-Lining Guilt

“But how do they work if they don’t have heaps of chemicals?” Easy — our leakproof underwear uses a multi-layered natural system that locks in moisture and keeps leaks at bay without PFAS-laced waterproof coatings.

Each pair includes:

• An absorbent inner layer made from natural fibres
• A breathable moisture-wicking middle to keep you dry
• A discreet leakproof barrier that’s free from toxic coatings
• Custom absorbency levels tailored for everything from light spotting to heavy flow days

It’s smart design without the compromise. You get all the protection, minus the health risks.

4. They’re Designed to Last (Not Linger in Landfills)

Unlike disposable pads and tampons — or even synthetic undies that break down into microplastics — Fri Period’s reusable period underwear is built to last.

You can wash and reuse them again and again (they’re machine washable), cutting down on:

• Monthly waste
• Chemical exposure
• Cost over time

One pair can last for years, making them a gift to your body and the planet. (If Santa had a sustainability tracker, you’d be gold-star status.)

5. They’re Empowering, Cute, and Confidence-Boosting

There’s nothing cute about feeling anxious on your period. Or worrying about chemicals. Or leaks. Fri Period’s period panties are here to help you feel:

• Secure in your body
• Confident in your health
• Stylish and supported (even on heavy flow days)

Choose from cheeky cuts, boxer brief period underwear, high-waisted styles, or bikini fits that match your mood. Sizes range from XS to 4XL, because everyone deserves a better period — no exceptions.

Bonus: They’re so soft and comfy, you might just wear them off-cycle too. No judgement.

FAQs

1. What are PFAS and why are they in period panties?
PFAS are synthetic chemicals used for waterproofing — but they’ve been linked to health risks. Some brands use them in the leakproof layer of underwear. Fri Period does not.

2. Are all Fri Period products PFAS-free?
Yes — every single pair is made without PFAS or toxic coatings. Our fabrics are Oeko-Tex Certified and tested for safety.

3. How can I tell if other period underwear contains PFAS?
Check the brand’s transparency. If they don’t clearly state “PFAS-free,” assume it’s not. Look for third-party fabric certifications like OEKO-TEX STANDARD 100.

4. How do I wash PFAS-free period underwear?
Machine wash cold, hang to dry or tumble on low. No fabric softeners — they can interfere with absorbency.

5. Can I gift PFAS-free period undies to someone?
Absolutely! They’re thoughtful, empowering, and health-conscious — perfect for teens, first-timers, or anyone who menstruates.
