Menstrual panties for children and teenagers
Not our first rodeo
- maybe yours is
Three good reasons
That's why period underwear is genius for kids
They're not moving 🫡
Anyone who has ever used a pad has probably experienced at some point that the pad shifted, causing a leak, or that small hairs got stuck in the pad's adhesive.
The pad in period underwear is sewn in, so it stays where it should.
Looks like regular underwear 😎
We know how it is. You don't want to stand out. Even less so, perhaps, when you have your period. Both our period underwear and our period swimwear for teens look just like regular underwear and swimwear. It doesn't scream 'period' – no tampon string, no wings from a pad.
Non-invasive product ✋
Unlike a cup or a tampon, period underwear is a product that is worn outside the body.
Products that go inside the body require more mental effort. For example, you have to remember to change them to avoid the risk of TSS. With period underwear, that's one less thing to worry about.
