Optime I is very versatile protection, characterised by its lightness. Despite being so lightweight, it’s the best imag-

inable protection. We have combined a low profile with generous inside depth. This makes it easy to team with other

equipment and means that the ear rests comfortably. Optime I 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.
