I don't wear a lot of baseball hats, but will when shooting, and also wear a boonie type hat when fishing as I also had some skin cancer carved out of my face (like 5 rounds of Moh's) so trying to keep that from happening again if I can.I never wore hats and didn't really care for them. But I have little to no hair(been cutting my own hair with trimmers with no guard for 10 years now).
Last winter the doc found some basil cell carcinoma on the top of head and cut a fairly large chunk out. I decided then and there that I would start wearing a hat. So I used the winter to get in the habit but I still leave home at times without one.
So I keep one in my car now and try to wear it.
I still feel a bit weird wearing one, but if it can help ward off more head surgeries , it's worth it.
