I have been interested for a while. Black Friday deals made it reasonable to try a pair. I will be buying more sleep shorts. I ordered my regular underwear size and that seems fine. It was so relaxing to not have any internal irritants. I was worried about the clean up, but everything stayed really contained. I'm still a little hesitant to try day time underwear.

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!
