    Teen sizes are good for petites

    Big fan of the leakproof underwear already, but as a 5'2 petite, I find the smaller teen cuts better for my stature (i.e., they sit on my waist, not 1/3 of the way up my back).

    Great coverage

    The confidence this product provides is priceless. We all have to deal with this, why not take some stress away. My daughters wear theirs all the time, even when they don’t need to. They’re just that comfortable.
