The light grey .60 mm sits in the middle of Dunlop's nylon range, which runs from .38 up to 1.0 mm. Nylon has a warm tone and a bit of give in it, so a .60 suits acoustic strumming and rhythm playing where you don't want a hard, clicky attack. Standard teardrop shape with a rounded edge for a smooth release, and the raised Dunlop logo gives your thumb something to grip. This was Dunlop's first pick. Sold singly. Part number 44-060.
