How to Measure

Waist

Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

Reviews Summary

Last updated 2 months ago
Customers say these period underwear are comfortable and provide excellent leak protection, with many feeling confident and secure throughout their cycle. Users appreciate the no-show design that works well under clothing and the soft, stretchy fabric that feels like regular underwear. Many reviews mention the effectiveness for heavy flow days and overnight use. Common feedback includes that these run small, so sizing up is recommended. Some customers note the absorbent material can feel slightly heavy or thick in the crotch area. A few mention the protective coverage could extend higher in the back for better nighttime protection. Overall, customers praise the comfort and reliability.

Great fit. On the expensive side for me on a fixed income.
DMDonna M. P.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 week ago5 Stars
Literally so cute and somehow still makes me feel sexy while im on my period, which is quite rare for me (thanks to bloating and just feeling bloody in general). Of course they work great as well whichbis super important! So glad this pattern is offered in the style and leak protection size i was looking for!

Absolutely love and recommend them. I have quite a few pairs and they're the best decision I could've made. Super comfortable and I have no concerns about leaks. I have a very physical/demanding job and I can do it without concerns now

Returning customer. Knix has changed my life. Always impressed with the coverage and comfort of these underwear.
BSBrianna S.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 month agoAs ever…
Knix work well for my leaky bladder. Just know that what they call bikinis are what most other brands call high-rise. (Their high-rise are granny panties.😁). Order accordingly.
MSMyra S.Verified BuyerReviewingSuper Leakproof® No-Show Bikini - Rated 5 out of 5 stars1 month agoLove them!
I discovered Knix about four years ago and I am truly impressed with their leakproof underwear’s. I recently reordered and noticed that they are even better quality than the ones I ordered in the past- locks in odor and dampness better than before. I only ordered 3 new pairs because they are expensive, but I’m looking forward to getting more in the near future-if they are on sale.
