For years I have used golf gloves as shooting gloves. Cheap, last a good amount of time, wet does not cause problems with the dye in them, comfortable and thin enough to pickup small or thin things easily.
I buy a dozen rights and lefts at a time. They are sold as singles, right or left. My sons use the same size as I do so they go faster than you'd think. Nice clean set for the gun club, dirtier set for the field and worst set for a spare in the field box. That field box has saved many a hunt. Extra gloves, extra ear plugs, extra shell bags or vest, extra socks, extra hats. You name it and it is most likely in that box. And yes there are extra shooting gloves of all three degrees of use. It even has a few extra shells in there.
