Claire ★★★★★ Sep 10, 2026

The TENCEL modal is ridiculously soft, softer than any cotton boxer brief I've owned. The waistband actually stays put all day without digging in, which is rare for me.

Avery ★★★★★ Sep 8, 2026

I’ve been rotating between two pairs for three weeks now and the waistband still hasn’t stretched out or rolled once, which is rare for me. The TENCEL modal is noticeably cooler than my old cotton trunks during afternoon walks, and the full coverage means no mid-day adjustments. Definitely ordering

First pair of underwear that feels like I'm not wearing anything at all, but still gives full coverage. The TENCEL modal is ridiculously soft and the waistband doesn't dig in even after a full day of sitting at my desk. Already ordered two more pairs.
