I’ve been wearing these for yoga and they stay perfectly in place without any bunching. The merino blend feels cool and dry even during a hot class.

Samuel ★★★★★ Oct 20, 2026

The fabric is noticeably softer than most underwear I've tried, and it keeps its shape even after a few washes. I wore it during a long workday and forgot I had it on, which is exactly what I want.

I've been wearing these on hikes and they don't ride up or bunch under my leggings, which is rare for any thong. The corespun merino actually feels cooler than I expected, even on warm days, and it holds its shape wash after wash.
