I never hike without my floppy hat and sunglasses.

Ultraviolet rays from the sun are almost perpendicular to the top of your head, which means if you go around with no hat on you’re essentially asking nature to grant you a nice, convenient case of skin cancer.

Those same rays of the sun do a number on your eyes if unblocked. If you have bad eyesight, consider prescription sunglasses. I started buying them a few years ago and haven’t gone back.

I’m little less finicky about wearing sun screen (though I shouldn’t be), but I try to wear as much fabric barrier between skin and sun as I can stand.
