    Fabulous undies!

    Exactly what I needed. These are very comfy, well made, and do what they say they will. I just bought a bunch more. Very happy with these undies.

    J'utilise les Knix depuis environ 5 ans et je n'ai pas hesité à en offrir à ma fille. Les culottes sont confortables et le tissu ne tâche pas. Je les adore!

    Knix are the best underwear! I typically size down as they relax after wear. Period protection and comfort!

    Daughter loves them!

    My daughter is 16 and loves these undies. They are super comfortable and provide added confidence throughout the day. She wears them daily and doesn’t wait for her menstrual cycle.

    Great product

    I love these and feel confident again without having to wear a pad or panty liner the only problem I’ve had is they slide down. If I have to do any walking around they’re gonna end up under my butt!
