Why choose Masmi cotton period underwear?

  • 100% GOTS-certified organic cotton – the healthiest material for period underwear. That means no irritation of the intimate area, infections, yeast or chafing.
  • Masmi period underwear is hypoallergenic.
  • Masmi Reuse period underwear does not "rustle" while wearing because it contains no film (polyurethane, polyester, etc.) in the absorbent layer – 100% discretion and peace of mind in every situation.
  • Guarantee up to 100 washes without loss of absorbency! – As the only brand on the market we offer this guarantee for period underwear. When following the manufacturer's washing instructions, Masmi period underwear will retain its properties for up to 400 washes without loss of absorbency!
  • 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 marks on clothing after a full day at work/school and on bedding in the morning.
  • Best solution for first periods – high absorbency and long protection time combined with the easiest use compared to inserting a tampon or changing a pad give girls unmatched comfort during these important days – one pair is enough for a full school day.
  • Works brilliantly in extreme conditions – during workouts, trips, flights, travel, long meetings or conferences and other situations where changing a pad, tampon or emptying a cup can be difficult – you don't have to cancel your plans! They are an excellent solution for postpartum women, those with incontinence, discharge issues and for women with disabilities – saving time and money with exceptional comfort.
  • Planet-friendly fully biodegradable; no component was tested on animals; they contain no superabsorbents, films, plastics, synthetic fragrances or allergenic ingredients.
  • Economically the best choice among all intimate hygiene products!
Q&A:
  • Is it worth buying period underwear?
Among women who switched from pads, tampons or cups to period underwear, feedback is very positive. Most say Masmi underwear performs well even on heavy flow days.
  • Do you use a pad or tampon 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 one, you can use it 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 highly economical. One pair can last 3-4 years without loss of absorbency. With proper washing and drying care, this period can reach up to 6 years (note that they may last even longer, but absorbency will decline minimally – this change will be unnoticeable). 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. Additionally, the comfort is incomparable due to longer wear time – 12 h for underwear vs 3-4 h for pads or tampons.
  • Do you feel wetness in period underwear?
If period underwear is washed correctly, it does not lose absorbency and should keep up with drawing moisture into the absorbent layer.
  • Do period underwear leak?
No, period underwear do not leak if used and cared for properly. However, you should observe your body and adjust wearing time according to your flow intensity.
  • Does period underwear produce unpleasant odor?
No, an unpleasant odor may sometimes occur if you have an intimate infection.
How often should you change period underwear?
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. One you wear, the other waits clean for a change, but if you want to be sure you'll always have a clean pair ready, 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 menstrual underwear?

Masmi panties stand out from the competition 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 laboratory tests. They offer the highest absorbency (77–166 g vs 25–50 g in other brands) and an absorbency guarantee up to 100 washes (competition 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 menstrual panties safe for sensitive skin?

Yes, Masmi menstrual 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. Studies conducted 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 absorbs them within 4–8 seconds! Synthetic materials, e.g., polymers or viscose, can increase the risk of irritation, fungal infections or even long-term problems such as endometriosis, as indicated by studies of the American Endometriosis Association. 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 — minimizing the risk of infections and allergies. Masmi is the only brand to apply 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 menstrual panties cost-effective since their price is higher than pads?

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

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 exacerbate endometriosis symptoms — WHO studies indicate 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 menstrual panties during my period?

Masmi panties are designed for use even 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, which generates 500 billion single-use products worldwide each year. The Masmi factory uses solar panels and a closed water circuit, minimizing environmental impact. Choose consciously — check details at masmi.com.pl!

8. How should I wash Masmi menstrual panties to preserve their properties?

Wash Masmi panties at up to 40°C with 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 in competitors, as confirmed by Allegro rankings 2022–2024. Choose a model with appropriate absorbency and enjoy confidence — order at masmi.com.pl!
