Q&A

Is it worth buying period underwear?

Among women who swapped pads, tampons or cups for period underwear, opinions are very positive. Most admit that Masmi underwear passes the test even on the first days of the period with heavy bleeding. Remember to change a pad or tampon every 3-4 hours depending on period intensity – period underwear only needs to be changed 2 times a day. We recommend buying 2 pairs – one worn, the other waiting clean for change, but if you want to be sure there is always a washed and clean pair waiting on those days, you can get more pairs. The optimal amount is 3 pieces.

Do you use a pad or tampon together with period underwear?

Period underwear are designed to provide protection on their own during menstruation. There is no need to wear an additional pad, but if you feel more comfortable with a pad, you can wear it just like in normal underwear. You can also wear underwear for extra protection during your period when using a tampon or menstrual cup.

Are period underwear expensive?

Period underwear are very efficient and durable, so their purchase is definitely economical. One pair can serve for 3–4 years without loss of absorbency. When following the manufacturer's washing and drying instructions, this period can extend to even 6 years (remember that underwear can last even longer, but absorbency will gradually decrease – this process will not be noticeable). 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 underwear. Additionally, there is incomparably greater comfort of using underwear due to the longer interval between changes – 12 h for underwear vs 3–4 h for pads and tampons.

Do period underwear leak?

No, period underwear do not leak, provided they are used and cared for correctly. However, you should monitor your body and adjust the wearing time of the underwear to your needs depending on the intensity of the period.

Does menstrual underwear emit a bad smell?

A bad smell may occur sometimes when you have a vaginal infection.

Do you feel dampness in menstrual underwear?

If menstrual underwear are washed correctly, they do not lose absorbency and should keep up with absorbing moisture into the inner absorbent layer.

Tailored to your body – available in 4 sizes: S, M, L and XL

How to wash and care for the products?

  1. Wash before first use.
  2. After use, we recommend rinsing and/or soaking before washing.
  3. Can be washed by hand or in the washing machine with the rest of the laundry or in a separate laundry bag (if you prefer).
  4. If using a washing machine, wash at a temperature not higher than 40º.
  5. For proper care, use neutral soaps. Do not use chlorine, bleach, fabric softeners, natural oils or Marseille soap, as they may affect absorbency.
  6. Do not use a tumble dryer, as it may reduce absorbency.

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!
