Customer Reviews (5.0 / 5 · 5 reviews)

Charlotte ★★★★★

I was skeptical about the 30ml absorbency but these handled my heaviest day without a single leak. The seamfree edges mean no visible lines under leggings, which was my main worry. Genuinely forgot I was wearing them.

Ella ★★★★★

I wore these on an 11-hour travel day and completely forgot I had my period. The seamless edges mean no visible lines under leggings, and the absorbency held up way longer than I expected. Genuinely the most comfortable period underwear I've tried.

Nicholas ★★★★★

The 30ml absorbency handles my heaviest days without any leaks, and the fabric is so soft and slim I barely notice it's there. Finally found underwear that actually works and feels comfortable.
