Good idea, poor execution.
I got this because I liked the idea of the pull out flap in the bill. Problem is that it doesn't fit well (too big), and I got the size I needed according to the sizing chart. I got 2 of them and they both stretched out after just a few days of wear and became totally unusable. The bill of the actual cap is a great length on it's own.. but the flap you pull out is really long and ends up just getting in the way, so I ended up not using it. Good idea, but doesn't work.
ConsDoesn't retain it's fit, pull out flap too long, too stretchy.
