“Sharp hat but runs really small”

“I purchased the hat for a friend. I carefully measured my own head so I could be relatively sure that the hat would fit per the description. I was very disappointed when the hat arrived as the inner measurement was 1-1 1/2 inches short so that hat was way too small. I would have reordered a larger size but that option was not available. A small adult or child could probably wear the hat which I thought was stylish for trail riding, backcountry activities, etc. If the measurements had been accurate, I would have rated the hat 4 or 5 stars.”
