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 eco-friendly staple for daily confidence and a "barely-there" feel.

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

Worry-Free Protection

      Love these no show thong

      Loving these had a bay last year and tampons don’t feel great right now and these have been a lifesaver when I had light periods after getting an iud. Can wear all day without a second thought and they feel great.

      Works well

      I have been going to another company for my underwear for incontinence. Knox was having a great sale so thought I would try. Material is completely different and kind of unusual to get used to but once I got the correct size, they are bad. Works for they are needed for.

      5 Stars

      I love this brand and I swear by their undies! I have a light flow, so these are perfect for my periods. I dont recommend if you have a heavy flow, but they are great for what they are meant for!

      Comfy

      Comfy…sorta odd fit though.. Should they fit above or below hip bone?? Kinda shift while wearing from back to front which I’m fairly certain is non hygienic. Not really wearing due to fit.

      Fit Different

      I have what I thought was this exact style but unfortunately these ones are different and they don’t actually fit the same at all. Disappointed. Too much material that they roll up in the crotch part making them very uncomfortable.

      The idea is in the right place

      I think the V area is very thin. Therefore, I have had a bit of spillage. I would also suggest buying a size up. I purchased a large and I find it’s quite tight.
