Eli U. ★★★★★

The fabric is so soft and smooth, I forget I'm even wearing period underwear. It held up perfectly during my heaviest day with no leaks at all, and the boyleg cut stays put without rolling up.

Madison R. ★★★★★

I was honestly skeptical about the boyleg cut, but it doesn't ride up at all during my morning runs. Handled a 6-tampon day without a single leak, and the fabric is so soft I forget I'm wearing them.

Thomas ★★★★★

Wore these on my heaviest day and the boyleg cut didn't ride up once, which never happens with other period briefs I've tried. The 30ml absorbency handled a full workday without leaks, and the fabric honestly feels like regular underwear.
