A legendary club released in 2016. Callaway Golf XR16 4-wood (4-wood) S Flex Original shaft Headcover included (heavily used) Thank you for viewing. I've been using this club for about 8 years, so it shows considerable wear and tear. The headcover is included, but it's also quite worn. More forgiving than a 3-wood, and flies further than a 5-wood. This rare 4-wood (4-wood) is not often found on the market!
