Titanium is Discraft’s metallic-finish premium plastic. It’s in the grippy opaque class, with a shimmer in the fill that sets it apart from ESP.
It behaves like ESP: opaque, grippy, workable in the cold, and durable without going glassy. Sixteen moulds are listed in it, mostly drivers.
The finish is the reason to choose it. If you don’t care about the look, ESP is the same class with wider mould coverage.
