What are menstrual panties?

Menstrual panties are comfortable and gentle menstrual protection, which you wash and use again and again. The absorbent function is sewn into the panties and consists of several layers of organic cotton. Finally, there is a leakage barrier so you can be sure that the period panties does not leak.

Imse's menstrual panties are unique on the market as they can be washed at 60 degrees, are certified according to STANDARD 100 by OEKO-TEX and are manufactured in Europe.

Below you can read more about our materials, washing advice and answers to frequently asked questions.

Choose panty according to flow

Imse offers period underwear with four different levels of absorption. Higher absorption means both more layers in the absorbent core and longer protection both in the front and back of the panty.

How much you bleed is individual, but most people bleed between 40-100 ml during an entire period, i.e. approximately 1/2 dl - 1 dl.

Washing instructions period panties - can be washed at 60 degrees

Before first use:

Wash your panties once before using them for the first time. It improves absorbency.

After use:

• Rinse the panties in cold water and wring out.

• Put them in the washing machine straight away or hang them to dry until it's time to wash.

• Laundry day! Wash at 60 degrees together with your other laundry. Avoid both fabric softener and bleach, as this can affect the absorbency of the panties.

• Finally, dry. Let the panties hang to dry - then they will last the longest. Or use tumble dryers or low temperature drying cabinets.

Imse answers to frequently asked questions

How often do I need to change period panties? And how many do I need?
There is no simple answer - it is individual and depends on the flow and chosen absorption of the panty, but usually they last for use for 8-16 hours. Remember that you do not need to switch to period panties all at once, our recommendation is to start with 2-3 panties so that you can feel what suits you. Your flow and washing options will affect how many you need in total, as a pair of period panties can be used several times during a period after washing. Every time you replace a disposable cover with a reusable one, you are doing a good thing for the environment.

Why do period panties have different absorption? Don't you always want to use panties with maximum absorption?

It is always best to match your need for protection with a period panty. If you're thinking of disposable pads - there are night pads with more absorption, but if you don't need them during the day, you'd rather choose a smaller and more flexible pad. The principle is the same with period panties. Period panties are simply most comfortable when you follow your flow.

If you have several pairs of panties for different flows, is it possible to tell the difference between them?

Yes, the flow of the panty is stated on the size label in the panty.

Does Imse have menstrual panties for children and young people?

Regardless of age, Imse's period panties are a practical and good choice. The panties are available in sizes XS-XXL and fit many bodies. XS corresponds to size 146-152 cl (10-12 years) and S corresponds to 158-164 cl (12-14 years). Our period panties Bikini (available with light/medium/high absorption) was chosen by our young test group as their favourite, but it is individual.

Can you wear Imse's period panties during the night?
Yes! We recommend our two models with high absorption, High waist and Bikini. Both have back absorption all the way to the waistband. The high waist panty also has absorption at the front all the way to the waistband.

Which period panties are suitable as a back-up if I use a tampon?
Our models with light or lightest absorption are perfect for a smaller flow or as extra protection when using a menstrual cup or tampon. Thin, flexible and safe.

Why do I get spots/discoloration in the crotch?
The vagina has a low ph value that protects your abdomen. On textiles, a chemical reaction may occur where the color is bleached, which is completely harmless. On black fabric, this fading can become reddish. It is completely normal and nothing that is visible from the outside or affects the function of the panties.

Do Imse's period panties contain biocides, nanosilver or any antibacterial treatment?
No. We believe that there is no positive reason for adding this. Instead, we have focused on developing a quality product that can handle 60 degree washing.
