How to Use Period Underwear, Step by Step
-
Pick your size
A good fit matters, because gaps at the legs can lead to leaks. Use the size chart, even if you are between sizes. Kischt comes in XS to 4XL.
-
Put it on
Wear it like any pair of underwear. There is nothing to insert and no pad to stick on. It should feel secure without digging in.
-
Check it during the day
While you learn how it works for you, check it now and then. Your flow decides how long a pair lasts. Heavy days may need more changes.
-
Change when it feels full
Change it when it feels damp, full or uncomfortable. Keep a spare pair in a small bag. Put the used pair in a zip bag until you get home.
-
Rinse, wash and dry
Rinse it in cold water first. Wash it, then let it dry fully before you wear it again. Check the care label.
Can You Wear Period Underwear Without a Pad?
Yes. The protection is built in, so you do not need a pad. Kischt has three absorbent layers and a moisture barrier.
On your heaviest days, you can pair it with a tampon, cup or pad for extra help.

Tips for Your First Cycle
- Wear your first pair on a day at home.
- Check it a few times to learn your flow.
- Not sure yet? Wear it with a tampon or cup at first.
- Keep a spare pair in your bag.
- Pick a dark color, like Noir, if stains worry you.
- Keep a few pairs, so one can dry while you wear another.
Can You Wear It to Bed?
Yes. Put on a fresh pair before bed, and change in the morning. The Kischt protective part runs up toward the back. That gives extra coverage when you lie down.
