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.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
Customers say these thongs are comfortable and feel like regular underwear, with many praising their effectiveness for light leaks and daily wear. Many reviews mention the soft, silky material and good absorption capabilities. Users appreciate that they don't show under tight clothing like yoga pants and leggings. However, some customers report sizing inconsistencies, with several noting they needed to size up or down from their usual size. Common concerns include the absorbent pad placement being too far forward and not extending far enough back, causing potential leakage issues. Some find the front area bulky or thick, making them visible under certain clothing. While most customers love the comfort and protection, a few experienced chafing or skin sensitivity with extended wear.

This thong is an essential! They've updated the liner fabric which is an improvement from the previous pairs I've had. Always comfortable and confident wearing these on or just before my cycle.

Tara D.Verified BuyerReviewingPOS - Super Leakproof® No-Show Thong - Original - Rated 5 out of 5 stars1 week agoLife saver!
I was tired of having to remember panty liners - this is a game changer for minor bladder leaks (ever heavier ones)! One of the best purchases I have made lately. Not to mention the quality and fit.

Casey W.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 4 out of 5 stars1 week agoA little snug
They are a little snug fitting. So I should have gotten a size up but other than that they are great!
KKnix1 week agoHey Haylee,
Thanks for the feedback! We're glad you love them overall. Sizing can be tricky online, but we're happy they're working great for you!

Haylee C.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 4 out of 5 stars2 weeks agoKnix no show thong
Tight around hips, so visible bulge. Large would be to big in liner area and sag.
Joanne J. S.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 2 out of 5 stars2 weeks agoNot a lot of absorption.
It went through after mid day
Camille T.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 5 out of 5 stars2 weeks agoBest thongs Ive ever owned
I absolutely love these thongs, I haven't worn thongs in yrs due to always having to use liners, them not being big enough and bunching up. These are so comfortable. You are always protected, Front to back. I will definitely be buying more.
KKnix2 weeks agoHey Jessica!
This is amazing! We're so happy our Super Leakproof No-Show Thong brought back your love for thongs. There's nothing better than hearing our customers feel protected and comfortable!

Jessica P.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 3 out of 5 stars2 weeks agoThe fit is so weird
I bought these last November .. unfortunately bought 5 thongs, and they are awful. I feel like a sumo wrestler. Even the light absorbency ones I bought are so thick in the middle and they are SO high cut. $100 on underwear I can’t even wear them, such a bummer.
Elizabeth G.Verified BuyerReviewingSuper Leakproof® No-Show Thong - Rated 5 out of 5 stars3 weeks agoGreat Product!
I love the cut of this thong and find it super comfortable. I like wearing them as panty liners and find the absorbency to be adequate. I also love all the fun colours that this style comes in!

Great for discreet support
ChandlerReviewingPOS - Super Leakproof® No-Show Thong - Original - Rated 5 out of 5 stars1 month agoA good idea to have on hand !
This is a great piece to have in your drawer - it’ll get you through a spotting/light day while still feeling like you’re killing it in leggings or spandex shorts. Stays invisible as it’s not at all bulky like i was nervous of!
KKnix1 month agoHey Lian!
This is amazing! We're so happy our Super Leakproof No-Show Thong gives you that confidence and comfort without any bulk. Thanks for the fantastic review!
