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.

    Save money on tampons!

    This is my first time trying period underwear, and I'm a big fan! These are comfortable, reasonably priced, and the absorbency is as listed. I got the size small and they fit just fine. The only thing I'd say is that they are not truly "no-show" under tighter fitting pants as the gusset extends fairly far back. But that doesn't detract from my five stars!

    Perfect

    Les sous-vêtements avec protection est un game changer. Ils sont confortables et j’adore les niveaux de protection léger et modéré. Ce n’est pas trop encombrant et efficace. Il faut vraiment les porter quelques fois pour qu’ils s’adaptent à notre corps.

    Perfect Fit & Super Comfortable

    I’m very impressed with the fabric of these bikini underwear and that they are no-show. The light leakproof feature is exactly what I require.
