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.

- Rose G.Verified Buyer8 minutes agoRated 5 out of 5 starsFinally I can sleep in peace!
I bought this pair primarily for the first night because it's uncomfortable to use a disc until my first heavy flow day. Overnight however, is when the heavy flow sets in and I was sick of using pads for that. These boyshorts are amazing! I didn't have to worry about a pad moving all around, so I could sleep in peace. I'm fresh off my first night, and my sleep quality was so much better, plus they're much cuter than your typical "period panties". Super happy with my purchase and worth every penny!!

Love these undies. They are so comfy. I never have to worry about any incidents. I found I’m in between sizes and had to size down as once you’ve worn them a bit they do stretch a little.

Love the boyshort and chocolate color. It’s a much better color than black. It fits well and the super leakproof level of coverage is perfect as I’m using it for stress urinary incontinence. It works great!
