25 decibel noise reduction

The K2C magnet earmuffs deliver a noise reduction rating of 25 decibels and are designed for use without a face shield to fit directly into the side slots.

Pressure-free fit

Outstanding comfort and a pressure-free fit are felt through use of lightweight materials, bringing together compact and memory foam cushioned earpieces.

360-degree nesting rotation

When not needed, earmuffs are able to twist and nest evenly across the top sides of the helmet, so you experience less strain and more balance.
