Excellent product!
The cut is so cute and comfortable! I was uncertain about the cut, but it actually covers in all the ways it needs to without giving up a girly, cute flair.
So freeing from wearing pads every day for the last 20 years. Thank u for making these. No irritation or rashes, no smell. I ordered 1 pair at first and then ordered 3 more. Very soft. I do change and wash daily because I don't have enough for a week. Plan on buying at least 10. Little pricey but I was spending $30 a month on pads....so in the long run well worth it
Machine Washable: Wash with like colors, cold setting with mild detergent, do not bleach, iron, or dry clean.

A gusset is essentially a liner. It’s where you’ll find our leakproof technology. It’s built into the crotch section of the underwear.
Coverage at Knix comes in all shapes and sizes. If we’re talking about silhouettes,, we go all the way from thongs to boxers.
We also offer high rise styles, like the Leakproof UltraThin No-Show High Rise, that sits just above the natural waist and gives full coverage through the stomach, hip & bum.
For extra liner coverage, look for undies that have an “extra-long liner” (usually 10”-14”), like in our Dream Short. And our Ultra Zones+ also have full bum coverage, too.
Have a suggested style or coverage? Just let us know. We love the feedback!
