“Best seamless absorbent underwear"

- Women's Health

Product Description

These underwear feature our buttery soft fabric and offer a full bum and hip coverage, sitting near your belly button. Great for leak protection, the ultra-thin liner absorbs about the same as 2.5 super tampons or 1 regular pad’s worth. Get the protection you want from periods and light bladder leaks while feeling comfortable and worry-free.

High Rise Silhouette

Sits just above the natural waist. Full coverage through the stomach, hip, and bum.

Moderate Absorbency

Absorbs 2.5 super tampons worth of liquid—perfect for moderate flow days, light bladder leaks, and sweat. The carbon cotton gusset top layer keeps you dry.

Worry-Free Protection

Perfect for moderate period days, light bladder leaks, and sweat. Moisture-wicking liner keeps you dry and comfortable.

No-Show Style

Buttery-soft and smooth fabric gives a seamless look and feel. Disappears under clothes, even leggings.

Easy to Wash

Machine washable, just like your regular underwear.

    I’m disappointed

    I bought a three pack and when I got them 2 of the 3 seemed to be medium instead of the large I ordered. I know this because I ordered some mediums earlier this year and it’s the exact same fit. I’ve worn these for years and was surprised at this mixup. And I can’t exchange them.

    Super comfy

    I love everything about them. They lose one star because I find they roll down, there’s no grip or anything to keep them from slipping

    This was so cool and comfortable. Easy stretch but not loose and sizing was great.

    really good quality. the only reason it's not 5 stars is I wish the leak proof part was a just little longer (front to back)

    Heat seal seam let go

    I’ve been a Knix customer for many years. I was really disappointed in this set. The heat sealed seam let go while I was putting the first pair on. Now I’m concerned about the longevity of the other 2.

    Great quality

    Amazing quality and don’t get ruined in the washing machine. I’ve had other brands but they just disintegrate in the washing machine. These hold up great!!
