If you think about it (like I did), a golf glove's purpose is to provide you with "grip," when your hands get hot or sweaty.
But you grip the club in the PALM of your hand, not the back of it, so you don't need a solid piece of grippy leather back there.
So, we removed it (also in some strategic zones in the palm), and replaced it with a breathable, mesh-like material that allows heat to escape, keeping your hands cool, comfortable, and dry.
Speaking of which, getting soaked with sweat is the No. 1 reason most leather gloves wear out so quickly (not to mention it's just plain gross), so our designs helps your gloves stay drier and therefore last longer.
