I have seen, with good results, people wrapping thin cork first, then wrapping the leather over that. Also the gel stuff.

My self, I have just straight leather wrapped on my bars, and after initial conditioning it is supple and comfortable even without gloves. I love the look and feel, and its resilience to scrapes and tears is worth every penny. Would like to go with the sew-on elkhide stuff one day, if/when this ever wears out
