XS is breathing new life into coated strings. With its ultra-thin film coating on every wound string and unique polymer treatment on the plain steels, XS offers our highest level of protection for maximum life with an uncommonly smooth feel. XS is the most innovative coated string ever created.

LASTING TONE, MAXIMUM LIFE
A tremendous leap forward in coating technology allows the string windings to be completely protected from contaminants for lasting tone and maximum life.

INCREDIBLE STRENGTH & STABILITY
With NY Steel as its core, XS offers greater break strength and tuning stability which are only enhanced by our proprietary Fusion Twist technology.

IMPOSSIBLY THIN, ALWAYS TRUE
Thanks to an incredibly thin coating, every XS string stays true to the iconic DAddario tone.
