Leakproof Bikini Liner

LOVE the amount of coverage for leaks. I don’t need the protected layer to go all the way to the back. This is the only company that provides the just needs alittle protection in the gusset area. BUT it seems as though the amount of stretch is not the same on all ‘holes’. Wearing XL I have too much material around the back but a L it’s not stretchy around the waist. Hard to explain. Going to try boyshort and hope it fits better.
