    Nice fit

    I wish the underwear were priced more affordably. I love Nick‘s, but their prices are still too high.

    My favorite undies

    Medium absorbency is the way to go … in a Goldilocks kind of way. It’s so much more comfortable than the light and super ones. I use for sweat and urgency back-up. I hope these never go away. Would be thrilled to see more colors to add to my cheery underwear drawer.

    My daughter loves them

    She loves them so much she asked to buy more for everyday wear. My only wish is that there was a label with absorbency level

    Great fit and function

    I am definitely not a teen (in my 30’s) but I like the fit on these better than my regular Knix leakproof. For size reference, I’m 5’3” 120 lbs and a pant size 4. I purchased a Medium and the size was perfect!

    My daughter just started her period and the Knix Teen underwear help her feel so much better knowing she doesn’t have to worry about any leaks or embarrassing moments!
