Product Description

The Knix Light Leakproof No-Show Thong 3-Pack provides invisible protection against light leaks and sweat with a seamless, raw-cut design. Each pair features a moisture-wicking gusset that holds one tampon’s worth of flow while remaining completely hidden under tight clothes. This bundle is the perfect staple for daily confidence and a "barely-there" feel.

Comfort-First Fit

This thong style sits lower on the hips with minimal bum coverage.

Worry-Free Protection

Our original leakproof technology offers a barely there feel while patented bonded edges help prevent side leaks.

Light Absorbency

Absorbs 1 regular tampon worth of liquid—perfect for light flow days, sweat and discharge, and backup protection for heavy flow days.

No-Show Style

Buttery-soft and smooth fabric gives a seamless look and feel. Disappears under clothes, even leggings.

Easy to Wash

Machine washable, just like your regular underwear.

    Happy lady

    This thong is very comfortable. Also I can do my reform Pilates without fearing there will be a leak.

    Just what I need

    I use these mostly on non period days to catch the other fluids so I can feel fresh at work all day.

    They are a little thick for the part that goes in your crack but it’s necessary I think. I just pull them up a little higher and that helps

    Cute thongs but small

    They're nice thongs but unfortunately had to exchange size. They run small, in my opinion without a ton of stretch. For reference I'm 5'6 and 180lbs, waist 33inch. I had to size up to XL. Large fit in other styles though.

    PLEASE!! Listen to us Foopa girlies!!!

    I wish Knix would listen to us girlies with a foopa. I would love a thong with a fuller front panel that is a thong. I used to buy the “cheeky” and wear them backwards. They were perfect. These are now discontinued & now it’s hard to find a thong panty with a fuller, higher front so the panty doesn’t roll down if you have but if a belly.
