Lots of guys here don't wear orange or red because it's not required, but If you've ever had someone check you out with a rifle scope you'd think well about what IDShooter said.
I used to wear just camo and a couple of times when I'm glassing the area with binocs I've found someone with a riflescope pointed right at me.
It's a gut wrenching feeling. It's also why I try to teach my grandkids and fellow hunters to never use the riflescope for anything but shooting at game. That's what binocs and spotting scopes are for.
I just shudder at the thought of someone looking at me thru a rifle scope with a 2 pound trigger between me and a bullet coming at me. Wear a red or orange hat at least. I've never seen one on a deer or elk.
