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 am used to cotton underwear, with a brief that covers my bum, and is high rise at the waist. These come pretty close to being ideal for me for daytime use dealing with light bladder leaks. They come close to feeling like regular underwear!

Constant little leaks are no problem with these underwear. Comfortable and wonderful cotton. I've bought both XL and XXL and the size is fine with both. I'm a size 18 and the XL are snug but comfortable, the XXL are a tad looser, but definitely still fit.
