I’ve been wearing these for a few weeks now and they really do stay odor-free even after a long day at work. The fit is just right—snug without digging in.

Henry ★★★★★ Oct 21, 2026

The fabric is so soft and stretchy that I forget I'm wearing it by mid-morning, and the slim fit stays put without digging in anywhere. I've worn it two days in a row now and it honestly still smells fresh, which is a total win for a daily underwear pick.

I wasn't sure how merino would feel for underwear, but this bikini is incredibly soft and stretchy—no scratching at all. The lightweight fabric breathes so well, I forget I'm wearing it even after a full workday.
