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 bought these for my two daughters and myself. I only wish something like this existed years ago when I started having my period!! I use them for light bladder leaks - while my daughters use them for their periods - they also help absorb sweat - they have many uses! These panties are so comfortable, they feel just like a regular panty - but you have the added protection! We have all the colors - they are very soft. They wash well and will last for years to come. They fit true to size. It's up to you if you still want to wear a liner just in case - but we haven't had the need as they absorb very well. I'm very happy with my purchase. I highly recommend! Thank you :)

I bought these to try a different material and I absolutely love them!! The cotton is unbelievably comfortable and the gusset feels soft and not as wet as the polyester types, if that makes sense. The only thing I would note is that the liner isn't seamless and has one seam at the back that doesn't lie flat (isn't sewn down). It isn't uncomfortable at all though!
