Perfect for dancing, skating, school uniforms and stylish outfits! These comfy, stretchy tights have a ribbed waistband that won’t budge while the built-in liner prevents period leaks from ever happening. See how our patented, 3-layer leakproof technology works:
First layer: Moisture-wicking technology wicks away sweat and moisture while neutralizing odors.
Second layer: A super thin, highly-absorbent liner that holds the power of 3 tampons or pads.
Third layer: A secure, liquid-resistant outer layer keeps leaks from happening.

Both our activewear and underwear feature our patented leakproof technology. There are 3 super thin layers in the liner that wick away moisture, rapidly absorb blood, sweat & discharge, all while working to keep in leaks. That means your teen can squat, sprint, stretch and move without peek-a-boo tampon strings, bulky pad seams or embarrassing leaks.
The different absorbency levels refer to light, medium and heavy period flows.
That’s totally up to your teen! We have recommendations based on each product, but only your teen knows their flow and comfort levels.
Both the Leakproof Active Legging & Leakproof Active Short have a built-in liner with the holding power of 2 super tampons.
If your teen is wearing Kt’s Leakproof Leotard & Leakproof Tights, we suggest using them with a tampon or menstrual cup during their medium to heavy days. Wear them alone when you have a light flow.
Step 1: Give your underwear or activewear a quick rinse under cold water.
Step 2: Throw them in the washing machine with your regular clothes. Like-colors for activewear. Wash on cold with mild detergent (no softener or bleach).
Step 3: There are two ways to dry them depending on the undies you have: lay flat to dry for medium absorbency products and activewear, or tumble dry on low for high to super absorbency underwear.
Step 4: That’s it! No ironing needed.

Yes! You can return or exchange within 30 days of delivery, as long as the tags are still attached.

My daughter loves her tights for dance. You used to make pink tights ~ could you bring those back? Ballet dancers would love pink and convertable tights. Thank you!
Dancers need convertible tights, and leakproof ones would be a huge help!
My daughter has been using these during competition season for dance and we have been very happy with the quality
