Z-Line Zone SS delivers the glidey, slightly less overstable flight of the Zone in ultra-durable Z-Line plastic. This blend provides a stiff, long-lasting feel while maintaining the straight-to-slight-fade performance that makes the Zone SS ideal for touch forehand approaches, straight backhand upshots, and controlled putter drives.
 
Z-Line is Discraft's most durable plastic blend. This is a hard translucent plastic that is available in vibrant colors. Discraft claims that this plastic is the choice of pros under normal conditions for slow seasoning.
