Customer Reviews (4.8 / 5 · 5 reviews)

Hannah ★★★★★

The modal fabric is the softest thing I've worn all week, and it didn't lose that feel after a wash. The thick waistband doesn't dig in at all, which is rare for a brief this sculpting.

Jason ★★★★★

The high-waisted cut actually stays put instead of rolling down like my old pairs. Wore these through a 10-hour workday and forgot I had them on.

Julian ★★★★★

The modal fabric is unbelievably soft against my skin and the thick waistband stays put all day without rolling down. I've already ordered two more pairs because they're the first briefs that don't dig in at the hips.
