The 3M PELTOR Optime I earmuffs are lightweight hearing protection that can be easily combined with other protective equipment. They are ideal for medium-level industrial noise, such as that found in workshops, metal processing facilities, or printing shops, as well as for outdoor activities like mowing the lawn or trimming hedges. The earmuffs reduce noise levels by up to 28 dB. They feature ear cushions filled with a unique combination of liquid and foam. The generous space inside the cups helps to prevent heat and moisture buildup. The wide, soft cushions reduce pressure around the ears, allowing for comfortable wear even over long periods. The cushions and foam inserts are available as hygiene kits that can be easily replaced when damaged or worn, extending the product's lifespan. The earmuffs are available in versions with a folding headband, neckband, and helmet attachment, as well as models in high-visibility green.
