Product Description

This mesh style High Rise underwear offer full coverage for hips and bum. Experience the barely there feeling while still being protected. Great for leak protection, the ultra-thin liner absorbs about the same as 2.5 super tampons or 1 regular pad’s worth.

Comfort-First Fit

This high-rise style sits at the natural waistline with minimal bum coverage.

Sleek Mesh Panels

Strategically placed mesh side panels create a lightweight, breathable feel while adding a modern, flattering finish.

Worry-Free Protection

Our original leakproof technology offers a barely there feel while patented bonded edges help prevent side leaks.

Moderate Absorbency

It absorbs about 3 super tampons worth of liquid—perfect for everyday wear and extra protection during maternity and postpartum.

    Truly leakproof

    I’ve worn Knix ultra thin for several years. They truly work for small bladder leaks. Don’t wear anything else!
