Depends upon the temperature: If it's in the teens, the only thing exposed will be my eyballs, while I'm sitting.
If it warms up to, say 80 F (which it has, in the first week of November, even- that's SW Nebraska for ya!), I'll be down to an orange ball cap and T-shirt...... and because the deer won't move in that heat (they can't take thier winter coats off), I have to go after them, which means hiking, often in thick stuff....... If I could find a way to wear shorts without getting all scratched up, I'd do it!
I have used a net when the bugs are bad.
I use one for turkey hunting, but by November, we've always had a killing freeze ..... never had bugs bother me.
