Hannah Y. ★★★★★ Oct 12, 2026

Wore these on an eight-hour travel day and didn't have to think about leaks once, which honestly says everything. The heavy flow hold really does live up to the four-tampon claim, and the bikini cut sits flat under leggings. Only thing I'd change is wishing they came in more colors.

I was nervous about switching to period underwear, but these hold a full day's flow without leaking—wore them for 10 hours and felt completely dry.

Scarlett ★★★★☆ Oct 13, 2026

I was skeptical about the "four tampons' worth" claim, but these handled my heaviest day without a single leak. The bikini cut sits flat under leggings, though the waistband rolls a little when I'm bending a lot at work.
