    I have been a Knix girl for a few years now (I usually buy the essential no show thongs) - this is my first time buying the light leakproof styles, I ordered simply because I liked the colours & thought I'd give them a try! One thing I noticed is they're definitely more snug than the essential line, but I know that's because they design them that way for the leakproof aspect. I don't mind because I know they will loosen a little & form to my body with wear. I may be converted to the leakproof now, I appreciate that it will absorb excess moisture. Knix is my go to for all underwear, you literally can't feel them while you're wearing them. Also invisible under tight clothes which is a must.
