Eli ★★★★★ Oct 22, 2026

I’ve been wearing these for a week now, and the merino blend keeps me cool during my morning walk without any itch. The stretchy waistband stays put without digging in, which is a huge plus under leggings.

William B. ★★★★★ Oct 21, 2026

These are hands down the softest underwear I’ve worn, that merino blend really lives up to the description. The stretchy fabric moves with me throughout the day without any bunching or riding up.

I was a little skeptical about merino underwear, but this hipkini is incredibly soft and stretchy right out of the package. It stays in place all day without riding up, and the fabric feels breathable and lightweight.
