I have the Brooks leather wrap. It's nice, but has a seam. The new Velo Orange Grand Cru seamless wrap is really nice as well. Best bang for the buck is the Velo Orange elkhide sew on stuff. It takes some time and patience to sew on, but it is extremely comfortable. Use Proofide or a similar product on any leather handlebar covering.

If you need brown or black, the older seamed VO stuff is on sale.
