I have a bit of hearing loss from power tools and loud concerts. Therefore, I am concerned about further hearing loss.
My solution for hunting is a set of those ear plugs on a rope. They weigh practically nothing (9 grams), and just sit around my neck all day. If I get into a position where I have to make a quick shot, I wont bother with them, but if I have some time to take the shot I'll put them in.
I want to get some electronic earmuffs and give 'em a try, but they wouldn't fit over my full brim leather hat anyways so I'm not sure how much I'd actually use them.
