TaylorMade 360 XD. Taylor Made's 300 Series irons came in three formats - the 300 (a forged club aimed at lower handicappers), and the 320 and 360 series which were aimed at higher handicappers. Designed and built for added confidence and distance, 360 irons feature oversized heads, perimeter weighting, and a thicker topline for added confidence at address. The irons have progressively more offset throughout the set. A popular, easy-hitting club suitable for almost all abilities. The XD stands for Extra Distance - but, as far as we are aware, the set is identical to the standard 360 model. If anyone knows different - please let us know!
