    I love these boxers

    For the first time I can wear something around my waist that takes care of urinary incontinence worries and feel completely comfortable and relaxed. Thank you KNIX!

    So comfy

    I didn’t realize there would be tighter underwear underneath, but they are seamless with no tags so they’re quite lovely. And the outside is nice and roomy.

    Cute and comfortable! Can wear as pajama bottoms. I just wish the coverage went waistband to waistband. Otherwise, love these!

    Works but uncomfortable

    I had high hopes for these. Seemed like it would be perfect for me for sleeping. Unfortunately I find them very uncomfortable. They are big and bulky and they sit low on my waist. I am always trying to pull them higher and when im trying to sleep it just feels like a diaper. I thought pad were uncomfortable but this is worse. It does do as advertised though. Holds lots of fluid. I found other products more comfortable.
