Electronics ear muffs are nice but they get really hot in the Georgia sun. In addition, I've found I don't always get a good cheek weld when using ear muffs with my long guns. While all disposable ear plugs are cheap, some are about as comfortable and putting a stick in your ear. These are the plugs I use because they're soft and comfortable, yet provide 29db of noise reduction. They come individually packaged and have a convenient cord so you can hang the plugs around your neck when not in use. I usually cut the cord and simply put the plugs in my pocket between stages. Can be reused many times, yet I usually dispose of them after each match or practice session and open a new pack the next time around. Keeps things more sanitary that way. Get 4 pairs for $1.
