Very light weight hat. Comfortable against the head (I have a buzz-cut hair cut). The hat I originally ordered is a bit snug, I certainly can't get two fingers between my forehead and the hat band, so I am ordering anew allowing for my two fingers to fit inside the tape when I measure. I hope that will be sufficient for a comfortable fit. The  brim is broad and seems to adopt an appropriate curve front to back that doesn't impede my vision at all. I will update this review upon receipt of the larger hat. Okay, upon reflection and a brief walk in a very slight Colorado breeze, it is apparent that the very broad brim on this hat creates a condition where I incessantly wanted to reach up and secure the hat against take off. Solution, I ordered the T5MO. With its narrower brim the effect of the wind is minimized and the coverage is adequate to protect from the sun. The T5MO is also very lightweight, cool, and, as always, it makes me look suave. What more could you ask?
