    Excellent, comfortable fit!

    I didn't know what to expect from leakproof underpants, but had high hopes. And I am really happy with my Knix. Good fit, nice looking, great fabric feel, terrific colours, and leakproof! Nice to just slip on panties and be good to go, instead of having to stick in an incontinence pad (I know, life is hell). Thank you, Knix!

    And your customer service is excellent, quickly resolving a sizing issue, and another issue about one colour fitting different from other colours. I feel well taken care of.

    Zone Panties

    Been wanting to try these. I ordered the incorrect size and am awaiting my exchange. I'm going to like the full coverage in the back and it's even a little more coverage in the front. Knix has since created the 360 full coverage high brief. I'll try that next. I am post menopausal and I like that I have security in the event of a small urine leak. The fabric is nice an adapts to your body. They wash up easily. I hang to dry them.

    I have a friend that has urinary and bowel issues post radiation and she uses these Zone panties for both issues. Being a nurse I will recommend these to my patients with either of those issues. Thanks Knix.

    Awesome Ultra Leakproof Underwear

    I am in cancer treatment, and I have some issues that require I take some precautions. The Ultra Leakproof gives me some peace of mind. Great for urine incontinence and for GI distress. Would like to see the Ultra Leakproof in the Dream Short as well! Due to loss of weight, I had to size down so I am building up my underwear again. So worth it!

    My mistake

    I have seven pairs of regular Knix and didn’t realize I was getting Ultra when I ordered three pairs. Won’t order them again.

    Premature Stretching

    I ordered this pair and a competitor’s underwear the exact same day. I washed them in the same gentle lingerie soap on the same days. They are the same exact size. However, after 2 washes Knix have stretched so much I can’t keep them up and therefore can’t wear them. So basically I paid $50 ( with shipping) for underwear I could only wear 2x. Very disappointing.

    I am disappointed in the way they fit. I am pretty sure I ordered the right size; however, the crotch isn't wide enough and they are loose around the legs causing the crotch to sag. But they fit snugly and comfortably around the waist. I do like the the way they are padded and feel confident wearing them.
