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.

I love the way these underwear fit my body. I no longer wear control top as the underwear sit in the right spot leaving my curves smooth. Will definitely buy in all colours.
