Playing in South Texas in the humid hot days, I go thru at least 3 to 4 gloves a round that become wet. So I've come up with ways to try to keep them longer by alternating them thru the round and then I wash them after 3 rounds. Tip is don't put them in the dryer after washing, I lay them flat on the dryer to let them dry.
I use the Kirtland golf glove and by doing the steps above, I can keep gloves at least 6 months for a 4 pack.
