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.

As usual I ordered the wrong ones. But I’m happy with them. They have protection from front to back. Gives me more confidence.

HHannahReviewingSuperPlus Leakproof® No-Show High Rise Black / XL - Rated 5 out of 5 stars4 days ago5 Stars
Fini le jetable !
Fini les serviette sanitaire lavable étirantes !
Couleurs pas trop tachante.
Jamais taché jusqu’ici (bien sûr il faut éviter l’eau chaude)
Fini les boutons pression de serviette sanitaire lavable qui font mal quand on est assise !
Suffisant pour mes plus gros flux jusqu’ici.
Mon seul souhait : plus de couleur peaux dans se modèle (tons de bruns comme dans d’autres modèles)
Bonne qualité résistant au temps et lavage/séchage
