Heavy flow menstrual panties

The best heavy-flow period panties on the market should be hygienic products that are cool and feminine, highly reliable and discreet, Oeko-Tex certified, available for all body types, and made from organic cotton.
Louloucup offers a variety of styles for heavy and very heavy flows: colorful or plain black panties, bloomer cuts or high-waisted styles, sailor stripes or beautiful black plumetis mesh.
One of Louloucup’s priorities is to cater to as many women and teens as possible. That’s why most of our styles are available from size XS to XXXL.

A menstrual flow is considered heavy when it is between 50 and 70 ml. For reference, a menstrual cup holds 25 ml. Louloucup period and hygienic panties reliably handle even the heaviest flows.

A menstrual flow is considered very heavy when it exceeds 70 ml. It is often linked to the use of an intrauterine device, more commonly known as a copper IUD. This non-hormonal contraception often causes quite intense bleeding that tends to ease over time.

• to naturally absorb heavy periods,
• to manage heavy bleeding caused by a copper IUD,
• to manage lochia and other discharge during the postpartum period,
• to manage a heavy flow during the night,
• to handle a strong flow on a busy day (commute, travel, etc.)

All day long.
The Louloucup period panty is designed to be worn for many hours. The goal is to free you from your period, to help you forget about it.
However, it always depends on your flow. If you’re worried about saturation, always keep a spare period panty or a menstrual cup with you. Louloucup offers both, Made in France, soft and super gentle! :)

Absolutely! In fact, these are the styles we recommend for a peaceful, leak-free night.
Our heavy-flow period panties have such a high absorption and protection capacity that the blood is held in the different layers without saturating.
You stay dry all night long. No leaks, no stains. You feel protected and pretty. You enjoy a good night’s sleep.

Louloucup has thought of all women.
To manage hemorrhagic, intense and heavy flow, the Clara and Mathilde period panties are recommended.
These two comfortable high-waisted models have a wide absorbent area that extends from the front to the back of the period panty. Your period blood is thus optimally absorbed and held.
The Clara and Mathilde panties have an absorbency equivalent to 5 tampons. You’re wearing full-coverage, ultra-reliable panties. You can enjoy a peaceful night’s sleep without worrying about staining your sheets.

The two black styles, Clara and Mathilde by Louloucup, are two types of ultra-absorbent period panties designed for very heavy flow. These period panties have a very high absorbency, equivalent to 5 tampons!
These two styles are among the most absorbent on the French market. Their production requires specific expertise and additional technical fabric. This explains a slightly higher unit price than for the other styles.

Clara and Mathilde panties have a unit price of €33.90, while the other heavy-flow styles (Fanny, Simone and Lou) are €28.90.
