Avery G. ★★★★★ Sep 10, 2026

I was skeptical about the price but the TENCEL modal really does feel different from regular cotton—almost cool against the skin. The waistband stays put without digging in, even after a full day of chasing my toddler around.

Violet ★★★★★ Sep 8, 2026

These are absurdly comfortable—the TENCEL modal is so smooth and cool that I forget I'm wearing anything at all. The full coverage is perfect for me and the soft waistband doesn't dig in even after a full day.

Aurora ★★★★★ Sep 8, 2026

The waistband actually stays put through a full workday of sitting and moving, which is rare for me. The fabric feels noticeably smoother than my cotton pairs, and they’ve held their shape after a few washes.
