I purchased the shirt thinking it was a nylon (per ad) supplex like many of the other brands' hiking shirts. Note that the fabric listed on the shirt is not nylon, but is polyester. I purchased the shirt in white. Between the polyester fabric and the color white, the shirt is somewhat opaque/transparent. I did, unfortunately, like the shirt's styling and fit.
