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 (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 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.

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 issues such as endometriosis, as indicated by research from 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 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 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 — worldwide 500 billion single-use items are generated 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 do 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 from competitors, as confirmed by Allegro rankings 2022–2024. Choose the model with appropriate absorbency and enjoy confidence — order at masmi.com.pl!
