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.

I have never worn this style before, but they are so comfortable. They fit perfectly and provided great protection. No peaks. I had bought one to try it, and now am ordering more.

I'd been on the fence about leakproof undies. I'd always used daily liners and didn't think I needed leakproof. But my reusable liners (made by a small Canadian business) weren't compatible with the boyshort style I love. So I took a chance on these. I love them! The fabric is buttery soft, and I love the colour. And the leakproof gusset is exactly what I need these days.
