    I'm buying more

    These are a game changer. I've purchased other brands before, but I should've gone the Knix route way sooner.

    Cotton is wonderful

    Love the soft cotton. Waist elastic has changed since the last time ordered. Not exactly as comfortable as the wider elastic waistband.
