Cleveland Golf’s 588 hybrids feature a “Glide Rail” technology, which combines two rails with a center keel to decrease turf drag. This, Cleveland says, produces more lift and speed at impact.
I really like the way the rails perform on my Cobra Baffler hybrids, and think these would perform just as admirably.
The face of the Cleveland 588 hybrids are designed with variable thickness, producing better flight on off-center hits. An optimal center of gravity is created by weight savings from the wall constuction and a rear sole plug.
