Victoria I. ★★★★★

I was skeptical about a thong being this comfortable, but the stay-put waistband honestly does its job—no digging or sliding around during a full workday. It’s the first one I’ve owned that I forget I’m even wearing, and the sustainable fabric feels great against my skin.

Ruby J. ★★★★★

The waistband is the selling point for me—it stays put without digging in, which is rare for thongs. The TENCEL fabric feels almost silky against skin and breathes well during long workdays. I've already ordered two more pairs.

Samuel K. ★★★★★

Honestly I bought these expecting the usual wedgie situation but the TENCEL modal makes them feel almost weightless, like you forget you have anything on. The fabric is ridiculously soft against skin and they survived a full work day without shifting once. Definitely grabbing another pair in black.
