What’s a gusset?

Which styles have more front or back coverage?

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 the new SuperPlus leakproof with our longest front-back-liner.

Have a suggested style or coverage? Just let us know. We love the feedback!
