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!

La qualité est au rendez-vous : les coutures sont solides, le tissu est doux et résistant. Côté confort, c’est tout simplement exemplaire : on les oublie complètement une fois portées, aucune gêne, même après une journée entière. Et surtout, elles sont super discrètes sous les vêtements, même moulants – pas de démarcation, pas de plis. Un vrai coup de cœur, je vais clairement en recommander !
