Size seems to be a continuing challenge with me. The first one I received proved too tight to wear. I'd done all the measuring and checked the results against the chart for my size hat, but it was all for not. So, I sent it back and ordered the next larger size. This one fit. The hat has an incredible look, and its material will protect my head from both the rain and the cold. It's rakish for a rain hat, and I do encourage anyone in the market for said item to choose this one.
