Christopher H. ★★★★★

I was skeptical about trunks with built-in absorbency, but the mid rise fit stays put through a full workday and the 4.5" inseam doesn’t ride up. I’ve worn them for light days and even a sweaty gym session, and honestly, I forgot I had them on. The rainbow trim is a nice little mood booster every ti

Sophia ★★★★★

The inseam length is perfect under jeans—no riding up, and the mid rise sits exactly where I want it. Wore them through a full workday plus a commute and felt completely dry, even with the backup pad situation handled. Honestly, these make me forget I'm on my period, which is the highest compliment

Leo ★★★★★

The absorbency is legit — I’ve tested it on my heaviest morning and it held up without a single leak, and the 4.5" inseam means no riding up during my commute. The black with the rainbow trim is a nice touch too, subtle but fun.
