Driver, 3W, 3H & putter, one more if you count the alignment stick cover. I use that one to keep the sticks from wearing a hole in my other head covers. You know, a cover to protect my covers.I find it funny that guys get worked up over covers. Put fluffy purple covers on all your clubs for all I care.
I don't understand why this is a thing to worry or expend even a modicum of energy/thought about.
Having said that, I do question covers for alignment sticks.....head scratcher for me.
