Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated yesterday
Customers say these underwear are extremely comfortable and feel like wearing nothing at all. Many appreciate the confidence they provide for light period days, unexpected leaks, and as backup protection. Users frequently mention the no-show design works well under tight clothing without visible lines. Common feedback includes sizing running small, with many recommending sizing up for better fit. Several reviews note the absorbent area could be longer in front for better coverage. While most praise the comfort and effectiveness for light flow, some experienced leaking issues. The fabric is described as soft and high-quality, though a few mention breathability concerns and rigid seams.

I’m not using this for periods, but rather the after-the-kids-later-in-life issues. First of all, these are the most comfortable underwear I have ever worn and the leg openings feel like there is nothing there (I swear my varicose veins are better without the tension). (Large size was comfortable for my daughter and I and our weight ranges from 130-140lbs.) They are completely invisible panty lines too. Yesterday I walked 9 miles in them and never once had to readjust them because they stayed exactly where they should be and were very breathable. They do absorb well and prevent leaks to clothing as well as keeping odor free. It does feel slightly damp for about 15 minutes, but even if you press tissue against a wet pad, nothing will come up, the moisture is immediately locked in, so maybe it’s my brain fooling me. After about an hour the pad seems to dissipate the moisture and the pad is thin again and ready to absorb again. I would never have booked a 3-4 hour tour where I might not find a bathroom before. Amazing technology that I wish I had had growing up, but thankful I have it now!!
