    Amazing panties

    I put on my new Ultra Leakproof High Rise, feeling a bit tight (normal) and didn't think or feel them again for the rest of the day. I know when I need the coverage they give, it will be there. Thanks KNIX!

    Happy my daughter bought me some

    I am so satisfied with them that I bought 3 pair of the men’s leak proof for my husband to wear after surgery.

    Won't order these again

    I like them except the leg openings are cut too high and the openings are too small. Because of these two things they cut into my legs and you can see the panty lines in my clothes.

    This is great for my daughter, no more leaking on the bedsheets! I was skeptical about them being able to hold enough blood, super impressed! And easy to clean!

    Not so leak proof

    I had high hopes. But when I stood up I felt wet. I ran toilet tissue over the outside of the panties and they had leaked. The fit is... odd. Or maybe it's my shape. The band around my butt was loose. The size fit is pretty true to size, but I think because of the thickness of the padded area, it doesn't conform right to the thigh/butt.

    Too small

    Ordered what should have been my size but they were too small. Then, I was unable to return them. The site said it was not available for return.
