    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!

    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.

    Cute and Effective!

    I was hesitant to buy these at first but boy do I wish I bought them sooner. Great for overnights, super cute, comfy, and protective. I’ve had 0 issues. Would recommend these to anyone!

    Great for pregnancy

    I have been wearing these during my third trimester of pregnancy, and they are so comfy, and feel so much more hygienic than my other pyjama bottoms.
