Putting Posture Corrector
Neutral, relaxed, right position for your golf grip.
‘Cozygolf’ is a golf assist gear company that made a handy wrist gear for posture correction of putter grips.
During lessons, the coach uses a golf ball for making space between the wrist and the putter grip so can do a neutral position. The reason why is that it has an ideal diameter that sizes the proper space with minimum contact points. So as you can see, the user wears it opposite.
