Product Description

Easy-to-wear underwear meets a new, must-have look. Soft modal spandex in a boxer-style silhouette with signature Knix logo waistband—in other words— these are your next favorite pair. Featuring our built-in leakproof technology so that you can use them as backup period protection or on their own on lighter days.

Comfort-First Fit

This French cut style sits at the natural waistline with medium bum coverage.

Worry-Free Protection

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

Light Absorbency

Absorbs 1 regular tampon worth of liquid—perfect for light flow days, sweat and discharge, and backup protection for heavy flow days.

    PERFECT FIT!

    These are my first leakproof so I decided to buy four pairs. I love the material and the wide waist band and as a bonus they are so comfortable to wear.

    Very comfortable

    I like these underwear (I have a large/round butt) so a lot of underwear slide inwards, but these have enough coverage to stay put. I would say it is a "generous" cut. I wear a small size.
