How to Measure

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.

Amazing! Highly recommended! <3
Tara W.Verified BuyerReviewingUltra Leakproof Zones+® High Rise - Rated 5 out of 5 stars1 month agoFinally leakproof panties that feels comfortable
After purchasing 2 other brands (Everdries 2 different sizes and styles) I thought ok Knix is more expensive but it’s either try these or forget about just panties and go back to pads. I’m please to say I’m very happy I tried them. Comfortable and reassuring I’m not going to embarrass myself. I’m 73 and had been experiencing occasional bladder leaks. Thanks for giving me my dignity back.
