WHY DO WE LOVE THE HIGH-WAIST CUT SO MUCH? 
A high waist is pretty, it’s elegant. It also meets a real need for emotional security. Feeling well supported lets you completely forget you’re even wearing protection. You go about your day with total confidence and without stress. And remember that during your period your tummy can be bloated, so a high waist offers that welcome gentle support.

Finding the right size, the right cut and the right quality is a first step, but the success of your plus-size period underwear also and above all depends on its absorbency.

The most effective washable period panties for managing very heavy periods (especially with an IUD) feature a specific double absorbent layer. This reinforced gusset area captures fluid instantly. It keeps the skin dry for longer and can handle an intense flow for many hours at a stretch.

Louloucup very heavy-flow period panties (Clara, Liv, Jade, Mathilde) can absorb up to 60 ml of blood without saturating.

Plus-size period underwear is therefore a very serious alternative to conventional disposable products for very heavy flows. It reduces the need for frequent changes and trips to the bathroom.
These plus-size period panties provide essential peace of mind during unpredictable cycles. They guarantee effective support all day long.

For sleeping, you can absolutely rely on plus-size period underwear. Period panties are actually highly recommended at night if you prefer to wear a cup during the day.

The absorbent panel of plus-size period underwear extends very high at the front and back. This extended coverage effectively blocks leaks no matter what sleeping position you adopt.

Plus-size period underwear keeps you fully protected at night. No more waking up to stains on the sheets. The Jade heavy-flow plus-size panty is the perfect ally for sleeping without a second thought: this washable period underwear is organic, soft, designed for very heavy flow so ultra-absorbent, and truly very comfortable.

Finally, the fabric used is breathable and very comfortable. You don’t feel any unpleasant sweat. You feel free to move while staying perfectly protected.

OUR TIP
For a worry-free, stain-free night, we recommend the menstrual shorty Mathilde or the Jade very heavy-flow period panty. Whatever you choose, we always recommend going for a very heavy-flow style. That way you have absolutely nothing to worry about!

Every stage of your cycle now has a suitable textile solution. The freedom to choose your protection boosts your everyday comfort. The range meets each specific need precisely.

Beyond performance, the safety of what we wear directly against our skin is an absolute priority for intimate health. Let’s talk fabrics, composition, certifications and organic cotton.

Every Louloucup style features a full lining in organic cotton. This natural fabric prevents the irritation often caused by synthetic materials. That’s a major advantage for your everyday comfort.

The GOTS label imposes very strict criteria throughout production. It bans the use of chemical pesticides and GMOs on crops. This certification also guarantees decent working conditions for textile workers.

✅ Big fan of cotton? So are we! The plus-size Léo and Jade styles are made from organic cotton inside and out! For even more softness, comfort and breathability.

Using a plus-size period underwear is much safer than wearing chlorine-bleached tampons. Organic cotton limits exposure to the chemical substances that disrupt the hormonal system. Your internal balance is therefore better preserved.

This fabric also reduces the risk of yeast infections and itching. Unlike the plastic used in disposable pads, this material lets air circulate freely. Moisture doesn’t stagnate and bacteria can’t proliferate.

And here’s the little eco bonus: choosing plus-size period underwear reduces your production of polluting waste. This eco-friendly choice protects both your long-term health and the environment. It’s a truly sustainable solution.

The Oeko-Tex Standard 100 tests every component of the garment, from the thread to the accessories. 

This label scientifically proves that the product is harmless to human health. It’s a reliable, widely recognized safety indicator.

The entire Louloucup range meets this demanding, rigorous standard. The brand refuses to compromise on users’ health and safety.

And in case you didn’t know yet: all Louloucup period panties are guaranteed PFAS-free and free from silver nanoparticles, as confirmed by lab tests. You’re wearing a plus-size period panty that fully respects your health and intimate area. No harmful substances penetrate your skin while you wear it.

Once you’re reassured about the composition, you still need to make sure your plus-size period underwear is so comfortable you forget you’re wearing it in every situation.

You can wear plus-size period underwear:

• During the postpartum period. The softness of organic cotton and the wide support band help with recovery. Comfort remains the priority during this specific phase.
  
  
• During your workouts. For yoga or running, plus-size period underwear stays put. It doesn’t move and never gets in the way, even during intense exercise. The reinforced support secures every movement. You can move without fearing the slightest leak. This also applies to the most dynamic daily activities.

Plus-size period underwear is also versatile for small mishaps and can be worn in case of light urinary leaks. This can happen sometimes when you laugh or make a sudden physical effort.

⚠️ There are absorption limits for this specific use. These styles do not replace protection designed for severe incontinence. However, plus-size period underwear is perfectly adequate for minor everyday leaks.
The feeling of freshness lasts a long time. Breathable fabrics prevent odours and constant dampness. You stay comfortable and confident from morning to night.

Plus-size period underwear is also great for discretion, especially if you choose a seamless style. Seamless or flat-seamed period panties leave no visible lines. They’re effective even under skinny jeans or a very light dress.

Choose seamless styles for a naked-skin effect. It guarantees a smooth silhouette.
