  • Highest absorbency (up to 77 grams of fluid) – that’s more than 4 super-size tampons. A guarantee of comfort and protection throughout the day or night. No stains on clothing after a full day at work/school and no marks on bedding in the morning.
  • The best solution for first periods high absorbency and long protection combined with the simplest use compared to inserting a tampon or changing a pad give girls unmatched comfort on those important days – one pair is enough for a whole day at school.

Q&A:
  • Is it worth buying period underwear?
Among women who switched pads, tampons or cups to period underwear, feedback is very positive. Most say Masmi underwear performs well even on the heavy days of their period.
  • 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 underwear for extra protection when using a tampon or menstrual cup.

  • Are period underwear expensive?
Period underwear is very efficient and durable, so the purchase is definitely economical. One pair can last 3-4 years without loss of absorbency. If you follow the manufacturer’s washing and drying instructions this period can be up to 6 years (remember the underwear may last even longer, but absorbency will slightly decrease – this change won’t be noticeable). The cost of pads or tampons over a similar period is 3 to 6 times higher (depending on the brand) than buying 2-3 pairs of underwear. Add to that the incomparably greater comfort due to longer time between changes – 12 h for underwear vs 3-4 h for pads or tampons.
  • Do period underwear leak?
No, period underwear does not leak if used and cared for properly. However, you should monitor your body and adjust wearing time according to the flow intensity.
  • Do you feel damp in period underwear?
If period underwear is washed correctly, it does not lose absorbency and should keep up with absorbing moisture into the absorbent layer.
  • Do period underwear leak?
No, period underwear does not leak if used and cared for properly. However, you should monitor your body and adjust wearing time according to the flow intensity.
  • Does period underwear emit an unpleasant odor?
No, unpleasant odor may sometimes occur when you have an intimate infection.
How often should period underwear be changed?
You need to change a pad or tampon every 3-4 hours depending on flow – period underwear only needs to be changed twice a day.
  • How many pairs should I buy?
We recommend buying 2 pairs. Wear one while the other is clean and ready, but if you want to be sure you always have a freshly washed pair available, you can get more. The optimal amount is 3 pieces.


Designed to fit your body - available in 4 sizes: S, M, L and XL

1. How do Masmi panties differ from other period underwear?

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

2. Are Masmi period panties safe for sensitive skin?

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

3. Why choose organic cotton instead of cheaper alternatives?

Organic cotton, as used in Masmi panties, is healthier for intimate health because it is grown without chemical pesticides and fertilizers, eliminating the risk of harmful substances entering the body — the vaginal mucosa can absorb them within 4–8 seconds! Synthetic materials, e.g., polymers or viscose, can increase the risk of irritation, fungal infections or even long-term issues such as endometriosis, as indicated by research from the American Endometriosis Society. Masmi offers the natural protection that cheaper products do not.

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

The GOTS (Global Organic Textile Standard) certificate guarantees that Masmi panties are made from organic cotton, produced in an environmentally and health-friendly way, without toxic chemicals or heavy metals. It confirms the highest safety standards — no pesticides, dioxins or chlorine, which minimizes the risk of infections and allergies. Masmi is unique in applying such strict criteria, which sets it apart on the market. Check details at masmi.com.pl and see how important this is for your health!

4. Are Masmi period panties cost-effective since they are more expensive than pads?

Yes, Masmi panties are an investment for years! One pair has an absorbency guarantee for up to 100 washes, which can be up to 5 years (approx. 60 periods), while 10 packs of pads or tampons last 10–12 periods. With absorbency from 77 g to 166 g (significantly more than 25–50 g from competitors) and no need for frequent changes, you save time and money. It’s an economical choice long-term.

5. Can Masmi panties help with health issues, e.g., endometriosis?

Yes, Masmi panties can support intimate health, including with endometriosis. Organic cotton, free from dioxins and chemicals, reduces the risk of irritation and hormonal disturbances that can worsen endometriosis symptoms — WHO research indicates a link between dioxins and this condition. The breathable structure and hypoallergenic properties of organic cotton additionally protect against infections.

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

Masmi panties are designed for use for up to 12 hours thanks to absorbency from 77 g (standard) to 166 g (triple absorbency), outperforming competitors (25–50 g). They are ideal for day, night or travel — no need to change every 2–3 hours like with tampons or pads, providing exceptional comfort. Care for them according to the instructions (wash up to 40°C without bleaches), and they will serve you for years. Learn more at masmi.com.pl!

7. Are Masmi panties ecological?

Yes, Masmi panties are 100% biodegradable thanks to organic cotton instead of plastic. They reduce menstrual waste — worldwide 500 billion single-use items are generated each year. Masmi’s factory uses solar panels and a closed water circuit, minimizing environmental impact. Choose consciously — check details at masmi.com.pl!

8. How do I wash Masmi period panties to preserve their properties?

Wash Masmi panties at up to 40°C with a neutral soap, avoiding bleaches and tumble drying, which guarantees up to 100 washes without loss of absorbency (even up to 400 with proper care). It’s simple and ecological — instructions are at masmi.com.pl. Start caring for yourself and the planet today!

9. Do Masmi panties leak during heavy periods?

No, Masmi panties do not leak even during heavy menstruation thanks to triple absorbency (up to 166 g). That’s more than the standard 25–50 g from competitors, as confirmed by Allegro rankings 2022–2024. Choose the model with appropriate absorbency and enjoy confidence — order at masmi.com.pl!
