Our BOLT Earmuffs are designed for adjustable, comfortable wear. These cap-mounted earmuffs provide an adjustable fit thanks to the center-mount design. The earmuffs allow for balanced wear with a 360-degree rotational arm that can pivot to multiple storage positions when not in use. The comfortable, pressure-reducing cushion helps avoid pressure and discomfort during extended wear. These earmuffs have an NRR of 24 dB, are CSA Class A, and are part of the BOLT System for securing accessories simultaneously on MILWAUKEE Safety Helmets and Hard Hats.
