I like the weight, colour, how cool (temperature) I stay while wearing it, and the sun blocking effects.
I am quite disappointed in the sizing (I'm usually a "mens" medium but I ordered the "Standard" extra small) because the sleeves and hood are too short for the torso but a bigger size means the torso is a tent on me.
I am also disappointed in how easily the fabric gets picks/pulls. I wore it for about 2 hours and got 3 visible pulls in the front of the shirt, 2 under my arm, and 1 on my back.
