The Optime 98 is very versatile protection, characterized by its lightness. Despite being so lightweight, it’s the best imaginable protection. Peltor has combined a low profile with generous inside depth. This makes it easy to team with other equipment and means that the ear rests comfortably. The Optime 98 is the natural choice when you need to use all-round protection for both short and long spells. It is first-rate for use in environments with moderate industrial noise, such as workshops, sheet-metal shops and printing works, but can also be used to good effect outdoors, for instance when mowing the lawn or in connection with hobby and leisure activities.

The Optime 98 is one of the most versatile earmuffs in industry today as it delivers the proper protection needed for a broad range of work areas with increased noise levels. When assessed noise levels reach up to 98 dBA, there is no better choice earmuff than the Optime 98.
