Diamond is Gateway’s premium clear plastic: a translucent, durable TPU blend with more grip than most clear plastics claim. Nine moulds are listed in it, and there’s a Hemp run with fibre in the fill.
That’s the Gateway plastic for holding flight. Translucent premium plastics stiffen in the cold and give up grip when wet, though Diamond is on the grippier end of the class.
Gateway’s own range has grippier options in Hyper Diamond and NXT. Diamond is the one you buy for lifespan.
