Yes, during hunting seasons, at least firearm hunting seasons, blaze orange for us hikers is a must. Bow hunters have to get close enough that they can tell a human from a game animal, so I don't worry much about them.

When I found out that cougar season here is year-around, I made sure the late Hysson (my avatar), too much like a cougar in color, was always in bright colors.

I was able to find a couple of blaze orange vests on sale at 2 for $5. (Note--that was 15 years ago, so probably at least double that now.) They were big enough to fit over me and my pack. I wore one and cut down the other for Hysson.
