3M PELTOR Optime II earmuffs were developed for demanding, high-noise environments – significant industrial or construction machinery noise, e.g. airports and agricultural work. They also attenuate very low-frequency sounds effectively. Sealing cushions with a special liquid-foam filling give a perfect fit and low pressure for maximum comfort even in long use. Ventilation channels in the cushions remove excess heat and moisture. Foldable for easy storage and transport. Attenuation: 31 dB.
