Product Description

Zero lines, total confidence. The Teen Light Leakproof No-Show Bikini is designed to be completely invisible under your tightest leggings, skirts, and school uniforms. Featuring a seamless, raw-cut finish, it provides a smooth look while offering a built-in safety net for light days, discharge, or sweat. Absorbing about 1 regular tampon’s worth of flow, it’s the perfect no-show period underwear for teens who want a "barely there" feel without the bulk of a pad.

Comfort-First Fit

Bikini silhouette with a classic mid-rise fit, medium hip and bum coverage.

Light Absorbency

Absorbs 1 regular tampon worth of liquid—perfect for moderate period days, light bladder leaks, and sweat. The carbon cotton gusset top layer wicks away moisture from your skin.

No-Show Style

Made from our signature buttery-soft PerformaStretch® fabric, it appears invisible under clothing.

Easy to Wash

Machine washable just like regular underwear.

    Wow

    Honestly, I’ve created a monster with my daughter. She refuses to wear anything but Knix underwear! It gives me peace of mind having the leakproof underwear as she ages!
