Glove or no glove is a personal preference and should incorporate a number of factors when a player is deciding what is best. The primary purpose of a glove is to enhance the quality of a player’s grip on the club. What factors affect quality of grip?
-The type of grip on the club and its age
-How well does the installed grip react to moisture (sweat, rain, or recently applied lakewater when testing flight conditions)
-How sweaty your hands get
-Susceptibility to blisters, etc.
I have been playing golf all of my life without a glove. I do not have particularly sweaty hands. I have full chord grips so moisture does not affect performance too significantly. I play regularly so I have developed calluses making blisters less of an issue. (A quick note on blisters: Blisters can tell a lot about how you are gripping the club. The location of regularly forming blisters can tell you that you may be gripping the club incorrectly (too much in the palm or in the fingers) or that you may be gripping the club too tightly.)
Golf gloves are a necessity for many players given certain factors during full swings but are often unnecessary and potentially detrimental in short game situations. I especially prefer bare hands in these situations where “feel” is of paramount importance. Dave Pelz often refers to the “Dead Hands” grip in his short game bible because it allows players to feel the weight of the club and prevents the small muscles (hands, forearms, and in cases upper arms) from taking over these shots and creating inconsistent results. Golf gloves create one more barrier between the club and myself, which can may diminish my control and feel for the club when it is most important.
