Knixteen

Period underwear for teens. Same great leakproof technology, now available in sizes for tweens and teens!

How It Fits

Extra coverage through the hip and bum, and sit slightly higher than our bikini silhouette. The stretch tech means these will relax a bit more than the Everyday line.

Fabrication

Body: 77% nylon, 23% LYCRA®
Gusset Liner: 86% cotton, 10% spandex, 4% carbon
Gusset: Fresh Fix Technology®

Care

Machine wash cold with mild detergent, do not bleach, lay flat to dry.

They work great for LBL caused by running and are fantastic on lite period days.
