Oversized! Bigger Than it Oughta Be
I wear a 7 1/8 fitted hat, and S/M is the size that works for me in all flexfit style hats. This hat is way too large on my head, practically swimming. I purchased this hat in colors, and both suffer from this. Oddly, the 2017 version of this hat, called the Tour Delta Textured Hat fits as it should in a S/M. The two of those I purchased hit just fine.
