What is Period Underwear?

Period panties are meant for wearing during menstruation, as a sustainable replacement for disposable products such as pads and tampons. Period underwear can be used as a protecting garment for light and even mild urinary incontinence.

Period underwear looks and feels just like regular underpants, and that is the great innovation! It doesn’t feel thick or clumsy despite consisting of numerous layers of absorbent fabric.


How does it work?

Instead of using liners or pads, use underpants that appear ordinary on the outside, but are sewn out of several layers of ultra-absorbent fabric in the absorption area, and made of an exterior leak-proof fabric.

After the use, the underwear can be washed in cold water and then washed. After drying, it’ll be ready to be used again.

If you’re a beginner in the world of period underwear, we recommend trying them out on your lighter days of menstruation and not going straight to use them while your flow is the heaviest.

It is recommended to purchase at least one pair of underwear per each day of moderate or light flow.

For example: if your period lasts 5 days, it’s best to buy 2-3 pairs of underwear for heavy or extra heavy flow (depending on your own personal flow), and another 3-4 pairs for light or moderate flow.
Overall, 5-7 period underwear, depending on the quantity of your days of bleeding and the variation of flows.

For all those who suffer from ultra-heavy flow during the night, we recommend considering purchasing an additional pair or two of night-designated period underwear.
