Period lingerie has one unbeatable advantage that tampons and pads will never have: a healthy, clear and 100% transparent composition. Today, we’ve decided to chat with you about the fabrics, raw and natural materials that make up our period panties.


We already know all about organic cotton and have talked about it a lot here. It lines the inside of all our Louloucup period panties to ensure both comfort and breathability. But have we told you about organic bamboo? This natural fabric is really interesting!


You’re tired of disposable period products and traditional pads and tampons that are irritating, unreliable and made with who-knows-what? Try durable, washable and reusable period products instead! You’ve got options: panties, boxers, thongs, g-strings as well as high-quality menstrual cups and discs, proudly made in France, now increasingly available in supermarkets and pharmacies.


When it comes to composition, we can only recommend choosing natural materials and organic farming whenever you can! For a menstrual routine that’s comfortable and good for your health and intimate area, let’s take a closer look at bamboo period underwear. It’s a guarantee of quality and comfort, but not only that. It promises safe periods with no pesticides or PFAS, and no petrochemical or plastic derivatives!

Why the composition of period underwear matters so much

Why is it so important to choose organic period underwear made with bamboo or cotton?

Choosing reusable period products with a clean, transparent composition over disposables

Why choose fairly pricey washable protection when cheap disposable period products are available at the supermarket next door? Quite simply because of what they’re made of.


Yes, period panties, cups and menstrual discs have many advantages (comfort, absorbency, leak protection, etc.), but their number-one benefit compared with pads and tampons is undeniably their composition. While disposable tampons and pads kept us in the dark for decades about what they contained, we now know exactly what we’re buying when we order a pair of period panties.


At Louloucup, we are committed to communicating in a completely transparent way. On each product page, you’ll find its composition as well as where it’s made.


It’s so important to be informed about what we buy, what we wear and what we consume. Without that curiosity, we put our health at risk and end up using chlorine-bleached tampons full of petrochemical derivatives and pesticides.

Louloucup recommends… the Romy organic cotton and bamboo period panties 😍


  • A bold, solid red!

  • A feminine, sexy and daring cut.

  • Ultra soft and very safe, it’s made of 95% organic cotton on the inside and 95% organic bamboo on the outside.

  •  Romy absorbs the equivalent of  2 to 3 tampons. This makes it suitable for light, medium and normal menstrual flows.

  • It can also be worn at the beginning and end of the period for those with a heavy flow..

  • Made in Portugal, it’s produced in Europe.

  • Bargain price: €24.90.

The composition of Louloucup products: labels and certifications

Louloucup period panties stand out thanks to strictly controlled manufacturing. Unlike disposable sanitary products, which are often impregnated with PFAS (persistent toxic substances), Louloucup excludes these compounds thanks to laboratory testing (SMT LAB, 2022).


A recent study revealed that 100% of the period underwear tested contained PFAS, with levels reaching up to 77,000 ppm. These substances, linked to health risks (cancer, hormonal disruption), are absent from the Louloucup range, which is certified OEKO-TEX® Standard 100.


This certification guarantees the absence of pesticides, nanoparticles or petroleum derivatives. GOTS-certified organic cotton, like organic bamboo used in some styles, are natural materials free from pesticides, safe for both your body and the planet.


By opting for this type of period protection, each woman replaces up to 150 disposable products per year, reducing her period waste while protecting her intimate health and the environment.

Bamboo period panties: a natural fiber with multiple benefits

Why is bamboo interesting for period underwear?


Where does the bamboo fiber used in our underwear come from?

The textile fibre used in period panties comes from bamboo viscose. Contrary to popular belief, it’s not raw bamboo, but a fibre obtained by transforming the cellulose extracted from the stems and leaves.


The process begins with growing bamboo, an extremely fast-growing plant (up to 1 meter per day) that requires no pesticides or fertilizers. The cellulose is then extracted, dissolved in non-toxic solutions (such as sodium hydroxide), and spun into fibers. Modern methods, like lyocell, recycle the chemicals in a closed loop, reducing environmental impact.

The 5 unique benefits of bamboo period panties

Unmatched softness: The long bamboo fibers provide a soft feel, ideal for sensitive skin.

Superior absorbency: The porous structure of bamboo viscose allows absorption that is 3 times higher than cotton, without compromising comfort.

Breathable and moisture-wicking: the thousands of micro-spaces between the fibers wick away moisture and prevent maceration. That means less odor and fewer bacteria!

Naturally anti-odor and hypoallergenic: the antibacterial properties of bamboo limit bad smells and irritation.

A more eco-friendly choice: Bamboo absorbs 30% more CO2 than trees and requires 30 times less water than cotton.

“Choosing bamboo period underwear means choosing a cocoon of softness and peace of mind for your intimate area, even during your period.”

Louloucup bamboo period panties combine these benefits with responsible manufacturing. To choose yours, match the style to your type of period, your menstrual flow (light, moderate or heavy), as well as your habits, needs and body shape.

Bamboo or organic cotton: which material should you choose for your period panties?

Natural materials like bamboo viscose and organic cotton each offer distinct benefits.


Bamboo stands out with absorption up to 4 times higher, ideal for avoiding irritation. It also regulates body temperature, staying cool in summer and warm in winter. Its silky feel is similar to silk, while organic cotton remains a safe bet for its proven softness and transparent production.

“Proper care prevents odours and extends the life of your panties, while being gentle on your skin.”

The verdict: a matter of how it feels and what you prioritize

Bamboo stands out for its extreme softness and odor-control qualities, thanks to its antibacterial properties. It also offers natural UV protection, a rare advantage among textile materials.


Organic cotton, which is less absorbent, appeals thanks to its familiar feel and more transparent manufacturing process. Louloucup offers both materials, with special attention to traceability and the absence of toxic substances (PFAS, nanoparticles).


These natural materials ensure comfort and respect for the skin, with a lower environmental impact than disposable products, while lasting for several years with proper care.

Bamboo, cotton – or why not both with our Romy style?

Romy: the perfect balance of comfort, style and performance

Designed in Portugal, this pretty, bright red feminine style has a rather bold cut that beautifully highlights the hips. Ideal for light to medium flows, this model absorbs the equivalent of three sanitary tampons.

How do you choose the right size and absorption level?

For optimal effectiveness and a great experience, choose your size based on your measurements: measure your hip circumference at the widest point and refer to the Louloucup size guide. Here’s an overview of the size equivalents:

Bamboo period panties FAQ

Why is a period panty made from bamboo fiber such an interesting option?

Bamboo is a natural material with some great benefits for period underwear: highly wicking, ultra soft, body-safe, breathable, odor-resistant, moisture-wicking and antibacterial.

Do bamboo period panties need special care?

Not particularly. Just take care of it as you would with all your other period underwear: rinse it well once you’re no longer wearing it, machine-wash it on a short cycle at a maximum of 30°C with a natural, non-greasy detergent. Finally, let it air dry away from any heat source (tumble dryer, radiator, hair dryer). Heat could damage its absorbent capacity.

How much does a bamboo menstrual panty cost?

At Louloucup, the **bamboo and organic cotton period underwear** Romy is €28.90 before discount! That’s already low compared with the competition. If, when you order, you add for example two more pairs of period panties, a menstrual bikini bottom and a cup, your Romy panties will then be €22.90 (just like all the other items in your basket). You’ll save €30. Plus, shipping is free, so go for it!
