Q&A:

Are period panties worth buying?

Among women who have switched from pads, tampons, or cups to period underwear, the reviews are overwhelmingly positive. Most agree that Masmi underwear holds up even during the heaviest days of their period.

Do you use pads or tampons together with period underwear?

Menstrual underwear is designed to provide protection during your period all on its own. No need to wear an extra pad, but if you feel more comfortable with a pad, you can use it just like with regular underwear. You can also wear the underwear as extra protection during your period when using a tampon or menstrual cup.

Are period panties expensive?

Menstrual underwear is highly effective and durable, making it a very economical purchase. One pair can last 3–4 years without losing absorbency. If you follow the manufacturer’s washing and drying instructions, this period can be as long as 6 years (keep in mind that the underwear can last even longer, but absorbency may decrease slightly—this change will not be noticeable to you). The cost of buying pads or tampons over a similar period is 3 to 6 times higher (depending on the brand), compared to buying 2–3 pairs of underwear. Plus, menstrual underwear is incomparably more comfortable to use because it needs to be changed less often—12 hours for underwear vs. 3–4 hours for pads or tampons.

Do your period panties leak?

No, menstrual panties do not leak as long as they are properly used and cared for. However, you should observe your body and adjust how long you wear them according to your flow.

Do you feel wet in your period panties?

If menstrual panties are washed properly, they do not lose absorbency and should continue to wick moisture into the absorbent layer.

Do your period panties leak?

No, menstrual panties do not leak as long as they are properly used and cared for. However, you should observe your body and adjust how long you wear them according to your flow.

Does your period panties emit an unpleasant odor?

No, unpleasant odor can sometimes occur if you have an intimate infection.

How often should you change menstrual panties?

You need to change your pad or tampon every 3-4 hours depending on your flow – Menstrual underwear only needs to be changed twice a day.

How many pairs of menstrual underwear should I buy?

We recommend buying 2 pairs of panties. You wear one while the other waits clean for a change, but if you want to be sure you always have a freshly washed and clean pair ready during those days, you can get even more pairs. The optimal amount is 3 pairs.

designed to fit your body—available in 4 sizes: S, M, L, and XL

How to wash and care for products?

  1. Wash before first use.
  2. After use, we recommend rinsing and/or allowing to soak before washing.
  3. Can be hand or machine washed with the rest of your laundry or in a separate laundry bag (if you prefer).
  4. If using a washing machine, wash at a temperature no higher than 40º.
  5. For proper care, we recommend using neutral soaps. Avoid using chlorine, bleach, fabric softeners, natural oils, or Marseille soap, as they may affect absorption.
  6. Do not use a dryer to dry your laundry as this may reduce their 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?
