I'm not 100% sure, but we put a 1.8 Lizard Skin on my DD's '15 Xeno and she loves it. I may still have the original if you want to go that route. DD prefers the Lizard Skin so we add them to every bat, but I save the originals just in case.
How does the thickness of the 1.8 compare to the factory grip? DD liked the feel of the Lizard grips from a demo day at the Nutter tournament, and she said she'd like a thicker grip if possible.
On my DD's 2015 Xeno we put the .5mm lizard skin grip over the existing LS factory grip. For some reason she didn't want to remove the original grip. I can't know how her brain works but everyone that has tried her bat thinks it feels great...
