Charlotte Q. ★★★★★ Oct 22, 2026

The fabric really is soft against the skin and doesn’t itch like other merino I’ve tried. I wore it on a long hike and forgot I had it on—no bunching or shifting at all.

William ★★★★★ Oct 21, 2026

Finally, a thong that doesn't dig in or ride up—this one's so light I forget I'm wearing it. The merino corespun fabric kept me dry on a long workday, and it’s genuinely softer than most cotton pairs I own.

The corespun fabric is surprisingly durable for such a delicate-looking thong, and it's been my go-to for long commutes without any irritation. No odour issues at all even after a full workday.
