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 1 month ago
Customers say these high-rise underwear are extremely comfortable and feel like wearing nothing at all. Many appreciate the smooth, silky fabric that provides confidence for light bladder leaks without the bulk of traditional liners. Users find them breathable, lightweight, and effective at staying in place without rolling down. The high waistband offers tummy support and works well under fitted clothing. However, sizing appears inconsistent, with many noting they run small and recommending ordering a size up. Some mention the waistband sits very high, which isn't preferred by all users. A few report issues with the absorbent area placement or coverage. Overall, customers praise their comfort and effectiveness for everyday wear.

They are okay but slip up. When it’s hot weather or I’m exercising they don’t breathe well.
Patricia S.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Last Call - Rated 5 out of 5 stars13 hours agoGreat Undies!
These panties are so smooth and comfortable that I really can’t tell that they are also leakproof… until I sneeze or cough and realize that I don’t need to worry about an embarassing leak!

Sheila M.Verified BuyerReviewingLeakproof UltraThin No-Show High Rise - Rated 4 out of 5 stars3 days agoVery comfortable
The reason I didn't give them 5 stars is that the hi rise are way too high for me. I'm 5' tall and always wear hi rise underwear but these almost reach my bra line. Therefore fey roll down making them a bit annoying. I will try and reorder one that fits me better.
KUKnix US 2.03 days agoHey Bill,
Thanks for your feedback! We're glad they're comfortable. We understand the high rise can be too high for some body types - definitely try a different style that works better for you!

TerriReviewingLeakproof UltraThin No-Show High Rise - Rated 5 out of 5 stars4 days agoMultipurpose underwear
I’ve been a fan of Knix from the start. I wear the underwear not only on leaky days, but they’re my go to on gym days and cycling days too. I’ve had the high rise for a long time but this time I sized down and they’re great. They don’t roll down for me in the smaller size and feel like a completely different underwear style.
