Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
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.

The lightweights were a game changer for my wardrobe. Have been a longtime customer & started with the super, but lightweights are great for light days & great for sweat control during the summer. So comfortably thin, they feel like normal underwear.

CLARA M.Verified Buyer - Rated 5 out of 5 stars1 week agoGreat fit
I got these so that my pre-teen would feel secure and fully prepared when she starts her period. She hasn't had to test their effectiveness yet but likes the fit and finds them comfortable for everyday use.
Bonnie H.Verified Buyer - Rated 5 out of 5 stars1 week agoSeriously, best underwear
I got three pair then loved them so much I bought three more. I wear them at the gym for weightlifting. I’m at “that age” where I don’t usually have a problem but when lifting heavy, I love knowing I’m covered. And no one can tell. Super product!
