Q&A : 
  • Is it worth buying period underwear?

Among women who have switched pads, tampons or cups to period underwear, the feedback is very positive. Most agree that Masmi underwear performs well even in the first days of a heavy flow. You should remember to change a pad or tampon every 3-4 hours depending on flow intensity. Period underwear only needs to be changed twice a day. We recommend buying 2 pairs. One pair is worn while the other waits clean for a change, but if you want to be sure you always have a freshly washed clean pair for those days, you can get more. Optimal quantity is 3 pieces.

  • 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 a pad, you can use one just as with regular underwear. You can also wear underwear for extra protection while using a tampon or menstrual cup.

  • Is period underwear expensive? 

Period underwear is very efficient and durable, so its purchase is definitely economical. One pair can serve you 3 - 4 years without loss of absorbency. With proper washing and drying care this period can reach up to 6 years (remember that the underwear may last even longer, but absorbency will decrease minimally – this process will not be noticeable to you). The cost of 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 underwear. Additionally, there is incomparable comfort due to longer time between changes - 12 h for underwear vs 3-4 h for pads and tampons.

  • Do period underwear leak?

No, period underwear does not leak if used and cared for properly. However, you should observe your body and adjust wearing time according to your flow intensity.

  • Does menstrual underwear emit an unpleasant odor?

 An unpleasant smell can sometimes appear if you have an intimate infection.

  • Do you feel dampness in period underwear? 

If period underwear is properly washed, it does not lose absorbency and should keep up with drawing moisture into the absorbent layer.

 

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?
