Yes to thin and delicate menstrual thongs for periods with elegance at the gym! For everyday life, an active lifestyle, or your workout session, you need period protection that’s durable, reliable, and absorbent, but also comfortable and, if possible, pretty!

The period thong is a period panty for light or medium flow that’s very appealing for several reasons: freer movement, guaranteed discretion, effective absorption.

For sports activities, it’s always better to wear an invisible period protection (no visible lines on your leggings!) that’s also reliable. Menstrual thongs then prove to be a great alternative!


If you’re still not convinced, find out everything about period thongs and especially how useful they are for sport. Organic, soft, zero waste, thin, feminine, absorbent – they’ve got it all! This period lingerie is a must-have for light to medium menstrual flows! 

Periods and sports: a central theme in a woman’s life

Sport and periods? A question many women have. Faced with common myths (it’s too dangerous, sport makes the pain worse, etc.), it has never been a better time to let off steam, move, breathe and sweat during your period.

And yes, exercise has many benefits

  • it may help ease period pain,
  • it may help you feel much better in your body, 
  • and it may also boost your mood (endorphins).

So, if you’re feeling well enough, slip on your prettiest menstrual thong for sports, roll out your mat, and go for a fitness session, yoga, Pilates, or cardio—whatever you like, the goal is to let off steam. You’ll see, you’ll feel better, proud, and calm!

And if you’re not feeling well, have no energy, are in too much pain or simply don’t feel like working out, that’s totally fine too! 😜 No pressure.

Which menstrual products should you use for sport?

To practice your favorite sport, you obviously have a choice of period protection. You can perfectly use:

  • disposable pads,
  • tampons,
  • washable sanitary pads,
  • the menstrual cup,
  • period underwear,
  • or a period thong.

Which menstrual product for which sport and which flow?

Which period and intimate protection should you choose for sports? Sanitary pads, panty liners, disposable tampons? 

Choosing your menstrual protection so you can practice your sport as calmly as possible will depend on several criteria (comfort, discretion, budget, etc.). Your menstrual flow and its intensity are crucial factors in choosing your protection.

If you have a light menstrual flow and you do a fairly gentle activity (yoga, Pilates, floor exercises)... ... you can absolutely wear a thong or a thin disposable sanitary pad.
If you have a light menstrual flow and you do a cardio sport (tennis, running, dance, athletics)... ... you can absolutely wear a menstrual thong, a period panty, or a tampon.
If you have a normal menstrual flow and you do a contact sport (judo, boxing)... ... you can wear period underwear or a tampon.
If you have a heavy flow and you do a water sport (swimming, water polo, freediving, scuba diving)... ... you can wear a menstrual cup with period swimwear or a tampon.

Period thongs: total freedom of movement!

Light, discreet period underwear for worry-free workouts: YES!

For sports, prefer a washable period panty that’s reusable and durable. This intimate and period protection is comfortable as well as absorbent. The washable menstrual thong has the advantage of being super discreet, a real plus for your workout!


This underwear is particularly suitable for:

  • In case of light or normal (not heavy) periods. Why? Simply because this underwear is minimally covering and therefore has little fabric and little absorbent membrane.
  • In case of spotting or small surprise leaks outside your period.
  • In case of various vaginal discharge throughout your cycle (brown discharge, white discharge, pink discharge).

For sports, these high‑cut period panties are ideal:

  • for dance (ballet, modern, jazz, contemporary, etc.),
  • for fitness, gym, Pilates or yoga,
  • for team sports (handball, basketball, volleyball, football),
  • for certain indoor sports (climbing, horse riding, golf, etc.)

Washable period thongs: pros and cons

The + points
Cons
Maximum discretion! A bit expensive upfront (compared with a box of tampons)
Practical: you can wear it for several hours. The shape does not offer optimal protection in case of heavy flow.
Durable: you can use it for years. Gets clogged and no longer absorbs properly if not cared for correctly.
Can also be worn outside your period in case of vaginal discharge or spotting. The high-cut shape of the thong isn’t everyone’s cup of tea.
Very feminine and sexy look.
If the composition is clean: it’s great for your health. No risk of allergies or irritation.

And what about heavy flow?

If you have heavy or very heavy periods, you have several options: 

  • you can absolutely wear a period thong, but you need to pair it with an internal protection such as a tampon or menstrual cup, 
  • you can also go for heavy-flow period underwear or very heavy-flow styles, 
  • you can also wear a menstrual cup.

The Louloucup period thong: feminine, organic and absorbent

Get to know this fabulous hygienic protection before adding it to your cart! 😉 

⊹ Sexy, black, lacy and feminine

Beyond being a piece of menstrual lingerie, it’s also above all a very pretty, feminine, and sexy underwear, elegant and light, in which you feel good and beautiful! Having your period doesn’t mean giving up your femininity! You can very well choose pretty models of organic cotton and lace thongs.

This pretty piece of feminine lingerie with a high-cut back flatters the buttocks. The thong sits between briefs and a string: sexier than briefs but less daring than a string, the thong is the perfect compromise. So it’s perfectly normal that it’s the favorite for many.

⊹ Made from organic cotton and manufactured in Europe

The black Louloucup menstrual thong is made from GOTS-certified organic cotton. Organic cotton is a natural material that allows the skin and intimate areas to breathe. It’s also very soft and pleasant, ensuring great comfort.

Tested and certified, this fabric is free from chemicals classified as carcinogenic (dioxins), AOX (halogenated organic compounds like chlorine), herbicides (glyphosate), PFAS, and insecticides. Our Louloucup menstrual thongs have the Oeko-Tex Standard 100 certification.

It’s a great alternative to tampons and pads: designed in France, fabrics from Italy, manufactured in Portugal (for Chloé). With ISO 9001, BSCI, and OEKO TEX 100 certifications.

⊹ For light to normal menstrual flow

Our tangas and Louloucup light-flow period panties are designed to absorb light menstrual flow. The absorbent membrane sewn inside the period panty effectively and reliably holds menstrual blood, as well as vaginal discharge (secretions) and light bleeding outside of periods (spotting).

Thus, the thong or light-flow period panty in cotton and lace perfectly replaces single-use disposable panty liners. This feminine hygiene period protection absorbs the equivalent of one to one and a half tampons, about 10 ml of menstrual flow.

FAQ – Washable period thongs

How do you wash period thongs?

Just like period panties, menstrual thongs should be rinsed in cold water, washed at 30°C, and air-dried. Feel free to check out our CARE TIPS section on the blog for all our washing tricks.

How much does a washable period thong cost?

At Louloucup, the Chloé style is on sale for €24.90!

I have a heavy flow – can I wear a period thong?

The menstrual thong is better suited to absorb a light to medium flow. You might experience some leaks if you wear a menstrual thong and have heavy periods. We recommend wearing a cup plus a panty if you have heavy periods, so you’ll be well protected!
