Period underwear with the highest absorbency on the market, made from the healthiest GOTS-certified organic cotton, grown without pesticides, herbicides or chemical fertilizers.

Our panties are a hypoallergenic product and hold as many as 4 certificates: GOTS, FSC, VEGAN and COTTON NATURAL.

These are reusable underwear worn during menstruation, replacing pads, tampons, and other feminine hygiene products.

  • Compared with menstrual panties from other manufacturers, which absorb up to 50 grams of fluid, these panties have triple absorbency: as much as 166 g of menstrual blood.
  • Regular period underwear has one absorbent layer, whereas these panties have four breathable absorbent layers made from special 3D fabric of organic cotton, guaranteeing maximum absorbency of the underwear.
  • Increased absorbency (166 g) – that’s more than 12 super-size tampons. This guarantees comfort and safety throughout the day or night. No marks on your clothes after a full day at work/school and none on your bedding in the morning.
  • Our panties have been rated the best underwear on the market by independent Allegro experts and other independent rankings – see here:

Q&A:

  • Are period panties worth buying?

Among women who have switched from pads, tampons or cups to menstrual underwear, reviews are very positive. Most admit that Masmi underwear passes the test even on the first days of a heavy period. You need to remember to change a pad or tampon every 3–4 hours depending on how heavy your period is – Menstrual underwear only needs to be changed twice a day. We recommend buying 2 pairs of underwear – you wear one pair while the other is already washed and waiting for a change, but if you want to be sure that on those days there is always a freshly washed, clean pair ready for you, you can stock up on even more. The optimal number is 3 pairs.

  • Do you use pads or tampons together with period underwear?

Period underwear is designed to provide protection on its own during menstruation. There is no need to wear an additional pad, but if you feel more comfortable with a pad, you can use one just as you would with regular underwear. You can also wear the panties for extra protection during your period when using a tampon or menstrual cup.

  • Are period panties expensive?

Period underwear is very efficient and durable, so buying it is definitely economical. One pair can last us 3–4 years without any loss of absorbency. If you follow the manufacturer’s washing and drying instructions, this period can be as long as 6 years (remember that the panties can last even longer, but their absorbency will decrease slightly – this process will not be noticeable to you). The cost of buying pads or tampons over a similar period is 3 to 6 times higher (depending on the brand of pads or tampons used) than buying 2–3 pairs of panties. On top of that, there is the incomparably greater comfort of using panties due to the longer time between changes – 12 h for panties vs 3–4 h for pads and tampons.

  • Do your period panties leak?

No, menstrual panties do not leak as long as they are properly used and cared for. However, you should observe your body and adjust how long you wear them according to your flow.

  • Does period underwear smell bad?

An unpleasant odor may sometimes appear if you have an intimate infection.

  • CDo you feel dampness in menstrual underwear?

If menstrual panties are washed properly, they do not lose absorbency and should continue to wick moisture into the absorbent layer.

How to wash and care for products?

  1. Wash before first use.
  2. After use, we recommend rinsing and/or allowing to soak before washing.
  3. Can be hand or machine washed with the rest of your laundry or in a separate laundry bag (if you prefer).
  4. If using a washing machine, wash at a temperature no higher than 40º.
  5. For proper care, we recommend using neutral soaps. Avoid using chlorine, bleach, fabric softeners, natural oils, or Marseille soap, as they may affect absorption.
  6. Do not use a dryer to dry your laundry as this may reduce their absorbency.

We are the only brand on the market that guarantees the constant absorbency of our underwear for up to 100 washes!

If you follow the manufacturer’s recommendations for washing and drying, Masmi period underwear will retain its properties for up to 400 washes!.

1. How are Masmi period underwear different from other menstrual underwear?

Masmi underwear stands out from the competition thanks to 100% organic cotton with GOTS certification, free from plastic, polyester, or synthetics, which minimizes the risk of irritation and infections (such as vulvitis, TSS), as confirmed by independent lab studies. They offer the highest absorbency (77-166 g vs 25-50 g in other brands) and guarantee absorbency for up to 100 washes (competitors max 60), without any rustling effect when worn or sitting. They are biodegradable and hypoallergenic. Allegro rankings 2022-2024 rated them the best on the market. Experience the difference at masmi.com.pl!

2. Are Masmi period underwear safe for sensitive skin?

Yes, Masmi period underwear is 100% safe for sensitive skin! Made from certified organic cotton (GOTS certified), they are hypoallergenic and free from toxins, pesticides, dioxins, chlorine, perfumes, or superabsorbents that can cause irritation or intimate infections such as vulvitis. Studies conducted by independent laboratories confirm that organic cotton minimizes the risk of allergies and disruptions to the vaginal microbiome compared to synthetic materials. Discover the comfort and safety of Masmi products – check them out at masmi.com.pl!

3. Why should you choose organic cotton over cheaper alternatives?

Organic cotton, like that used in Masmi underwear, is healthier for intimate health because it's grown without chemical pesticides and fertilizers, eliminating the risk of harmful substances entering your body—the vaginal mucosa can absorb them in just 4-8 seconds! On the other hand, synthetic materials like polymers or viscose can increase the risk of irritation, yeast infections, or even long-term issues such as endometriosis, as indicated by research from the American Endometriosis Association. Masmi offers the natural protection that cheaper products simply can't provide.

3. What does the GOTS certificate mean and why is it important?

The GOTS (Global Organic Textile Standard) certificate guarantees that Masmi underwear is made from organic cotton, produced in a way that’s safe for both the environment and your health, without toxic chemicals or heavy metals. It’s a mark of the highest safety standards—no pesticides, dioxins, or chlorine, which minimizes the risk of infections and allergies. Masmi is the only brand to use such strict criteria, making it stand out on the market. Check the details at masmi.com.pl and see for yourself how important this is for your health!

4. Are Masmi period panties cost-effective, given that their price is higher than pads?

Yes, Masmi panties are an investment that lasts for years! One pair is guaranteed to stay absorbent for up to 100 washes, which means up to 5 years (about 60 periods), while 10 packs of pads or tampons only last 10-12 periods. Thanks to absorbency ranging from 77 g to 166 g (much more than the 25-50 g offered by competitors) and no need for frequent changes, you save both time and money. It’s an economical choice in the long run.

5. Can Masmi panties help with health issues like endometriosis?

Yes, Masmi panties can support intimate health, including for those with endometriosis. Organic cotton, free from dioxins and chemicals, reduces the risk of irritation and hormonal disruptions that can worsen endometriosis symptoms—WHO studies show a link between dioxins and this condition. The breathable structure and hypoallergenic properties of organic cotton offer extra protection against infections.

6. How long can I wear Masmi period panties during my period?

Masmi panties are designed for up to 12 hours of use, thanks to absorbency from 77 g (standard) to 166 g (triple absorbency), which outperforms the competition (25-50 g). They’re perfect for day, night, or travel—no need to change every 2-3 hours like with tampons or pads, so you get exceptional comfort. Care for them as instructed (wash up to 104°F/40°C without bleach) and they’ll last for years. Learn more at masmi.com.pl!

7. Are Masmi panties eco-friendly?

Yes, Masmi panties are 100% biodegradable, thanks to organic cotton instead of plastic. They help reduce menstrual waste, which amounts to 500 billion single-use products worldwide every year. The Masmi factory uses solar panels and a closed water cycle to minimize environmental impact. Make a conscious choice—see details at masmi.com.pl!

8. How should I wash Masmi period panties to maintain their quality?

Wash Masmi panties at up to 104°F/40°C with neutral soap, avoiding bleach and tumble dryers. This guarantees up to 100 washes without losing absorbency (up to 400 with proper care). It’s simple and eco-friendly—you’ll find the instructions at masmi.com.pl. Start taking care of yourself and the planet today!

9. Do Masmi panties leak during heavy periods?

No, Masmi panties won’t leak even during heavy periods, thanks to triple absorbency (up to 166 g). That’s more than the standard 25-50 g from competitors, as confirmed by Allegro rankings from 2022-2024. Choose the right absorbency model and enjoy peace of mind—order at masmi.com.pl!
