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.

Check out our size chart here. If you want some help, we have virtual fitters ready on deck to help you find your perfect fit. Book a video call with them today.

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

Our collection is made to fit teen bodies. For leakproof activewear in adult sizing, please visit Knix.
