Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
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.

How to wash
Knix underwear is 100% reusable and machine washable, just like your regular undies.
Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.
Machine wash on a cold, gentle cycle with mild detergent.
For their longest life, air drying is best. Hang or lay flat to dry.
Fabric softeners, bleach, ironing, or heat from the dryer.

Rebecca L.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 4 out of 5 stars2 days agoSeaming changes are not comfortable
In the new pairs of Super Leakproof Cotton Bikinis I purchased, the back seam of the absorbent pad is not folded over on the inside of the underwear.
So there is thick seam rubbing on your butt or annoying you when you sit.
I am not sure if this was a production flaw, but they should go back to folding the seams onto the underside of the pad, so they do not rub on your skin
KUKnix US 2.09 hours agoHi Linda,
We're sorry to hear that the seam on your new Super Leakproof Cotton Bikinis is causing discomfort. We appreciate the detailed feedback about the seam construction.
We'd love to learn more, please reach out to us at info@knix.com with your order number. Our team will be happy to take a closer look and assist further.
Warmly,
Team KnixLinda A.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 1 out of 5 stars6 days agoUncomfortable changes
These are not the same as the cotton bikinis I purchased previously. The fabric is not smooth, soft, or as stretchy as the previous bikinis. The gusset is not sewn into the fabric and if the gusset shifts the cotton crotch becomes wet. The large seam across the back rubs and is uncomfortable. I purchased the same size as before but these are almost a full size smaller. Not worth the expensive price and I will not repurchase. Hopefully Knix reads reviews and takes them seriously as there are many negative reviews about the changes from the previous bikinis. I hope they will bring those back.
Kyra W.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 5 out of 5 stars1 week agoGood fit
I like the feel of the cotton and the cut fits me perfectly.
felis R.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 2 out of 5 stars1 week agoUncomfortable seam
I bought a pair of the previous version of these a while ago and loved it so I figured buying the updated version would be fine too. But while the extra lining is good, the seam lays across my backside weird and makes it really uncomfortable to move around in. I switched to leak proof because I hated the feeling of pads but this just feels like I'm wearing a pad all over again. It protects me great, but I just can't see myself reaching for this over my last pair or repurchasing.
Rebecca L.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 2 out of 5 stars2 weeks agoRougher material
I'm not a fan of the new material being used for the cotton. It's rougher and more irritating on the skin than the previous version of cotton underwear.
Jen C.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 5 out of 5 stars3 weeks agoLove them
Comfy, good fit, work well
Susan S.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 2 out of 5 stars3 weeks agoNot the same as the No Show Bikini
The leak pad is very bulky at the back. More geared for sleeping than daytime. These do not fit as well as the No Show Bikini. The backside is gapes on me.
Diana S.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 5 out of 5 stars3 weeks agoPerfect
Love the style and fit of these and the absorbency is exactly as stated. Absolutely perfect!
Cindy B.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 3 out of 5 stars4 weeks agoDifferent than the regular Leakproof Cotton Bikini
I bought these thinking they'd be the exact same as the Leakproof Cotton bikini but just with more absorbency. Unfortunately, the regular Leakproof Cotton bikini's aren't available anymore so I thought I'd give these a try. They are NOT the same! The waistband is thinner which disappoints me the most because this very thin elastic doesn't seem as comfortable as the original thick band. The fabric also seems slightly thinner. They just don't feel as good of quality. Please restock the Leakproof Cotton Bikini!
Genevieve S. M.Verified BuyerReviewingSuper Leakproof® Cotton Bikini - Rated 5 out of 5 stars1 month agoSwitching to Cotton!
This was my first pair of cotton from Knix and I am in love. I am going to replace what I have with cotton, moving forward. Its soft, comfortable, and theleakproof features are as trustworthy as all my other pairs. This color is cute, I'm hoping for fun cotton prints in the future as well.
