What is the best menstrual underwear?

The most made in France: Elia!

The most made in France, ecological, and safe menstrual underwear. It is signed by Elia.

Elia, the pioneering brand of menstrual lingerie in France, has taken on a significant challenge: to offer a product that is both safe, durable, eco-friendly, and made in France. The brand tests its products in laboratories, which are guaranteed to be free from PFAS, chemicals, and endocrine disruptors. Elia’s menstrual underwear is also tested under gynecological and dermatological supervision in real usage conditions for 28 days to suit all flows and all skin types, even the most sensitive. Effectiveness, durability, and absorption have been validated for the heaviest flows without loss of effectiveness for 5 to 7 years. A true revolution, far from misleading marketing claims. The brand says what it does and does what it says!

But innovation doesn’t stop there: each pair of underwear is knitted from certified organic cotton yarn, cut, and assembled in France. A true feat of made in France, which supports local know-how and a more respectful and sustainable textile production. Thanks to its engaged community, Elia manages to offer menstrual underwear certified Origine France Garantie, accessible to everyone, without compromising on quality.

With Elia, you choose much more than just a pair of menstrual underwear: you adopt a healthy, sustainable, and 100% French solution, certified B Corp, Positive Company, and committed against menstrual poverty and research against endometriosis. Don’t hesitate to check out the 17,000 verified customer reviews on the brand's website and online to confirm your choice!

A little bonus, the perfect Elia underwear can be purchased for €25 each and in packs for €18! So, who said that the prettiest lingerie wasn’t made in France and accessible?

Mademoiselle Culotte: breathable and detachable menstrual underwear

Do you know Mademoiselle Culotte? We share a part of the name with this brand, which is a good sign! More seriously, the French brand stands out with its innovative offer that goes beyond just underwear: detachable underwear for easier maintenance, breathable models for optimal comfort, seamless range for invisibility under clothing, and even menstrual swimwear. Among the best-sellers, we find Léa, the timeless model of the brand, Arya with its practical detachable system, and Céleste which focuses on breathability — note that these three models are available for teens.

The advantage of Mademoiselle Culotte menstrual underwear lies in their effectiveness: up to 12 hours of invisible protection under clothing, without odor or unpleasant dampness. The brand currently offers a particularly cool deal with one free pair for every two purchased, which can go up to five free pairs. In other words, enough to stock up without breaking the bank and anticipate the future. Unlike tampons and sanitary pads, underwear is obviously reusable for several years, adding a touch of responsible consumption.

To differentiate itself from the competition, Mademoiselle Culotte doesn’t limit itself to selling protections: the brand also offers a free mobile app for menstrual tracking, providing personalized support with advice and predictions tailored to each user. A little technological touch that we appreciate!

Zero seams, zero leaks, 100% freedom: the ecological innovation Louloucup changes the game.

Since 2017, the French brand Louloucup, led by a mother-daughter duo, has taken on a significant challenge: to combine record absorption with absolute discretion. The brand now offers underwear, shaping lingerie, swimwear, and menstrual cups. Designed to liberate women’s daily lives, the brand collaborates with textile engineers to provide solutions that combine comfort and aesthetics, far from the constraints of traditional disposable protections.

The Liv model, a true bestseller of the collection with a rating of 4.69/5, embodies this revolution. It stands out with a technical feat: its ability to manage very heavy flows (up to 50 ml, equivalent to 4 to 5 tampons) while remaining completely invisible under clothing. Thanks to its seamless design, the Liv underwear is forgotten, even under the tightest outfits. Gone is the “bulk” effect; welcome to incredible thinness that accompanies you all day with a total feeling of lightness and without the “wet” effect.

But performance would mean nothing without impeccable safety. Louloucup stands out by making your health a priority: each pair of underwear is made with OEKO-TEX® certified materials, a lining of organic cotton, and is tested free from PFAS. This guarantees healthy protection, free from endocrine disruptors, respectful of the most sensitive skin.

Inclusive and accessible, the brand offers sizes ranging from XXS to 3XL. By choosing Louloucup, you opt for a certified and ultra-comfortable sustainable alternative that simplifies your cycles without compromising your style.

On the budget side, excellence becomes affordable: the Liv underwear is offered at €32.90 each, and its price decreases: €25.90 from 3 pairs and only €22.90 in a pack of 5!

The underwear fighting against menstrual poverty: Repeat sold only in packs

Stay dry during your period without emptying your wallet? That’s the mission Repeat has set for itself! To fulfill its ambition to end menstrual poverty, the brand has imagined underwear at prices as soft as its cotton.

Its specificity? No single sales, but in packs of at least three pairs for the sweet price of €49.90. All your purchases can be paid in three installments, to offer all menstruators a healthy and sustainable solution, without having to invest all your savings! Reusable hygiene protections must be accessible to everyone, and that’s the brand’s mission.

In addition to ensuring you small prices, Repeat also guarantees quality and peace of mind. Its absorption technology based on bamboo fiber and its breathable fabric offer all flows, even the heaviest, unwavering confidence and well-being. All fabrics are certified OEKO-TEX Standard 100. Its total coverage at the front and back absorbs the equivalent of five tampons, a true alternative for heavy flows.

The cherry on top, it’s also all bodies that Repeat wants to take care of. Inclusive, the brand keeps its promise and addresses all menstruators by developing protections ranging from size 34 to 52.

“The Repeat menstrual underwear is ultra-comfortable even if it’s a bit thick (and not just in the crotch area). I wouldn’t wear it with tight jeans, for example, but otherwise, it’s perfect.

I’ve used this model over different cycles and I’ve only had a micro leak once despite my very heavy flow. It’s very easy to wash. Despite the uses and washes, the seams don’t wear out, but I feel like after multiple washes the underwear may lose some of its effectiveness.

Repeat sells its underwear in packs of three at a really attractive price! I even think it’s the most competitive brand on the market.”
