    Heavy flow approved

    I was skeptical that these would hold up as I usually go through a few ultra tampons in a days time. I was pleasantly surprised that they lasted on for 10 hours on their own, and could have been worn longer without any inkling of leaking. They are a little short but still comfortable, would definitely recommend!

    The leakproof leaked.

    Leaked the first night I wore them through the undies. Disappointed because I really wanted them to work!

    Parfait !

    J’en voudrais avec protection légère ou sans protection pour les autres nuits de mes cycles. Ils sont confortables, beaux, absorbants et sexy !

    Super cute but run so much bigger than all the other underwears. Need to exchange for smaller. I’m normally a M in everything Knix, but this needs a S or even XS

    Comfy and stylish

    I definitely feel cuter walking around the house in these instead of regular period underwear. The fit isn't great in the rear but no one is complaining

    Always happy with Knix

    I have several pair of the original boxers and decided to give the Mini Dream Boxer a try. Happy I did. Very comfortable and holds as advertised. Primarily used for bladder leak protection.
