    Best investment ever!!!

    I originally purchased the three pair of underwear on Amazon and fell in love so I went and bought three more from the Knix website because I really wanted to invest in good period underwear. These are a dream! I don’t have to worry about any leaks or smells or uncomfortableness when wearing these. Super absorbent especially for being so thin! I recommend these !

    Best invention ever

    I was skeptical at first but decided to give it a shot and my goodness these are amazing. I was always frustrated because when I wore traditional pads at night my period would go on every where but the pad. I had even tried the long ones and still they failed. I decided to give these a try and have no regrets. Best investment ever.

    Knix Ultra Leakproof ROCK!!

    Since receiving my Knix panties I haven't had any leakages on my outer clothing. I'm so happy I ordered from Knix since I had been using Everdries which caused me to leak on my clothes and yes, even on my car seat! NOT A HAPPY CAMPER!! So I googled what are the best 5 incontinence underwear and AI listed Knix as one. I did some research on Knix and placed my order. So glad I did!!

    Heavy duty protection

    So comfortable while also being super protective. It's nice to not feel like you're wearing a diaper while pretty much getting the effectiveness of one
