What Is Period Underwear?
Period underwear looks and feels just like your regular underwear — the only difference is that it has built-in technology to absorb menstrual blood (and other moisture like sweat, discharge, and even light leaks). That means you can wear them on their own, or as backup protection with a pad, tampon, or cup on heavier days.
At Kt, our period underwear is designed specifically for teens — so they’re seamless, comfortable, and sized for growing bodies.
How Does It Work?
It all comes down to the gusset (that’s the crotch area of the underwear). In regular underwear, it’s just two layers of fabric. But in period underwear, it’s built with three powerful layers that work together to keep you dry and protected:
-
Layer 1: Moisture-wicking and antibacterial technology that pulls liquid away from your skin and helps control odor.
-
Layer 2: A thin but super-absorbent liner that locks in period blood (holding anywhere from 3–12 tampons or pads worth, depending on the absorbency level you choose).
-
Layer 3: A leak-resistant outer layer that prevents spotting on your clothes.
So instead of worrying about leaks, you can go about your day with confidence.
How Much Can They Hold?
Everyone’s period is different, so Kt offers three levels of absorbency:
-
Medium Absorbency: Holds about 3 pads or tampons worth of blood. Great for light days.
-
High Absorbency: Holds 4–8 pads or tampons worth. Perfect for heavier flow.
How Do You Wash Them?
Super easy. After wearing, just give your pair a quick rinse in cold water, then toss them in the washing machine with the rest of your laundry. Use a mild detergent and avoid bleach or fabric softener. To dry, lay flat or tumble dry on low. That’s it — reusable and ready to go again.
Why Choose Period Underwear?
-
Eco-friendly: In the U.S. alone, billions of pads and tampons end up in landfills each year. Reusable underwear helps reduce that waste.
-
Comfortable: Unlike pads, there’s no bulky feeling — and unlike tampons, there’s nothing internal.
-
Stylish & versatile: They come in different styles and colors, so they look and feel like regular underwear.
So, Should You Try Them?
That’s completely up to you. Some teens prefer to wear period underwear every day of their cycle, while others use them as backup or just overnight. There’s no wrong way to use them — it’s all about what makes you feel the most comfortable and confident.
At Kt, we believe period products should work with you, not against you. That’s why our leakproof underwear is designed to support you through your cycle, your way.
