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 have a few different types of Knix and this is my favorite. Great length under everything! My only complaint is please give us more colors like more nude colors to wear under white pants. I know they are called "sleep" but I wear them all day long.

These are one of my favourite knix items/underwear in general. I love them for sleep and every day, soft, breathable, durable and so comfy. And doesn't feel large or bulky at all.

Super comfortable material. Great fit, wonderful for bladder leaks and hot flash sweat! Just ordered more! They don't roll up on the legs and the waist doesn't roll down as some others have described. Band on waist is comfortable as well.
