What our customers are saying
Customers say these underwear are exceptionally comfortable, soft, and feel like regular underwear without bulk. They appreciate the smooth, silky material that doesn't show lines under clothing and provides excellent absorption for bladder leaks and periods. Many note the high-rise style offers good coverage and stays in place throughout the day. Users find them durable, maintaining quality after multiple washes over years. Common praise includes the confidence and peace of mind they provide for travel and daily activities. Some mention sizing runs small and recommend going up a size. A few note concerns about recent design changes making them bulkier, and some find insufficient elastic around leg openings. Reviews consistently highlight their effectiveness for various needs from light leaks to heavy flow days.

    Back to the drawing board!

    I had high hopes (probably my own fault) for these underwear. I've been trying to find a replacement for my 3 year old Anti by Proof underwear. Seems they are no longer in business. I've been struggling with urine leaks for a few years now, and my Anti underwear contained it all without any noticeable odor. These do not. I decided to try going without a pad to see if I could wear them on their own. No leak through, but OH BOY did they SMELL! Can't do these. There is ZERO odor protection. I don't expect there to be NO odor, but this didn't even try. Guess I bought the wrong product. These are DEFINITELY FOR PERIODS ONLY! But, back when I was still having periods, there WAS a smell. I wouldn't recommend these to ANYONE unless they were wearing and changing frequently a super tampon. And ONLY as an emergency back up. You know, for a special event where you cannot afford to have an accident. But for ladies who want to be confident if they leak a little when they sneeze or cough, keep looking. The fit was good, that's why I gave them one star.

    Smooth Feel, Good Production

    I love these briefs. This is the 4 drop version. Smooth, not bulky but offers great protection from leaks.

    Elastic is not good

    I have bought these many times and this lot has different elastic. That does not stay up! Ugh!

    The original maker had a perfect product. Ever since then, they have really lost quality,primarily in the elastic choices. I do not know how many different ones they've tried, but they need to go back to the original elastic!!!

    Love this style

    This is my favorite style by far. I love how they fit. I have a curvy bottom and a small waste - and these simply fit and look great. I also really like the colours in this pack.

    Good

    Comfortable but do rise up when wearing shorts or a dress. They seem to stay when in pants. But do seem to be absorbent.

    Hey Andrea,

    Thanks for your feedback! We're glad you find them comfortable and absorbent. The no-show design works best under pants, but we appreciate you sharing your experience!
