Reviews Summary
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.

    So thin, they feel like normal underwear

    These underwear are great for any unexpected leaks, and they are thin enough that you can’t feel any padding. will be getting another pair

    I can't say enough good things about these. They fit perfectly and are perfect for light days or for added protection with tampons. I finally have peace of mind when my period comes now. They are truly no-show and very comfortable.

    Even wearing cotton underwear, I never felt dry. I bought a pack of these to just try them out. Now I am getting a few more packs

    I never go a day without my Knix!

    As with every pair of Knix I own, these are so comfortable and keep me feeling protected all day from light bladder leaks. They have enough stretch to still be comfy on the days I feel bloated, and making me feel safe if I start to spot before my period is expected to arrive.

    Awesome undies

    I received my first pair as a gift on a promotion outside in the byward market. Fell in love with them and just recently ordered more on the online shopping. Got them within 3 days n they are excellent. They are excellent for small leakages. I stay dry n not having to run for the bathroom.

    Comfortable Coverage

    I was looking for something as a back up that I could wear to work. It’s gives coverage for accidents and light days and is comfortable and doesn’t show panty lines. Got the three pack and they’re perfect.

    No-Show Bikini equals No Show Moisture

    I have been using this bikini for years and years.

    I just reordered more to go with my original orders.

    I use them for my gym work outs and travel. I use them

    on work days for times I might sneeze or giggle. For going on walks and wearing light colored pants.

    Not buying daily pads make up for the cost and so much better for the eco system.
