Elizabeth U. ★★★★★

I was nervous about leakage on heavy days, but these held up without any bulkiness. The slim fit is a game-changer—no visible lines under my work pants.

Emily ★★★★★

The 30ml absorbency handled my heaviest day without any leaks, and the seamless edge really does disappear under leggings. I've been wearing them all week and they stay put without riding up, which is a huge relief for workdays.

Emily Z. ★★★★★

These are the first underwear I’ve worn on a heavy day that actually feel slim and don’t show any panty lines. I was nervous about the 30 ml absorbency but it held up perfectly.
