MILWAUKEE® BOLT™ earmuffs are designed for all-day fit and comfort. These cap-mounted ear protectors provide an adjustable fit with their center-mount design. The earmuffs also allow for balanced wear with a 360⁰ rotating arm that can pivot to multiple stowed positions when not in use. The comfortable pressure-reducing cushion helps prevent pressure and discomfort when wearing the ear protectors for extended periods. These earmuffs have the NRR indicated to protect you from hazardous noise and are CSA Class A certified. Our earmuffs are part of the BOLT™ system which allows users to secure accessories simultaneously. Certified for use with MILWAUKEE® safety helmets and hard hats.
