My putter head cover never leaves the big pocket on the side of my bag. My driver and 3w head cover go in the cart basket upon first use and stay there. Obsessing about head covers might mean someone spent too much on their clubs. The guys with iron covers crack me up. I picture them sleeping Naked in bed with their clubs every night.
If you look at a “What’s in my bag” for a touring pro, most of their clubs look like well-used implements, beat to hell.
oh, someone mentioned pace of play. Golfers fiddling with their head covers can get annoying.
