1. The fear of leaking shouldn’t hold her back

Nothing hurts more than seeing your teen come home from school embarrassed by a period leak. For her, it might mean tying a sweatshirt around her waist, rushing to the bathroom mid-class, or worrying through a sleepover instead of enjoying herself. As a parent, it’s hard to watch and feel like you can’t be there to help at every moment, but you can make sure she’s prepared.

2. Sitting on the sidelines due to periods isn’t the answer.

Leaks don’t pause for practice. In fact, 1 in 2 teens skip sports during their period, missing out on the activities they love because of worry and embarrassment. While you can’t be at every practice or game, you can give her the protection and confidence she needs to focus on the game, not leaks.

3. Kt delivers the comfort & absorption, pads & tampons can’t.

Pads can feel bulky and uncomfortable, making it hard for your teen to focus on school, sports, or hanging out with friends. Tampons need to be changed frequently and aren’t always an option if your teen isn’t comfortable using them yet. Kt Leakproof Underwear offers a better solution: thin, no-show, and available in multiple absorbencies, holding up to 9 super tampons’ worth. She can move through her day comfortably, confidently, and worry-free.

4. Easy to wash, ready to wear again.

Kt Teen Leakproof Underwear are machine washable and super easy to care for. Just rinse, toss in the wash, and she’s ready to go, again and again. No more last-minute trips to restock pads or tampons each month. She stays protected and confident every day, while you save money and cut down on disposable waste.
