Helmet Ear muffs for Kask

Protection I for low to medium noise

Protection II for medium to high noise

Protection III for high to very high noise

Compatible with KASK, Petzl and Centurion helmets/hard hats (a lot more), they are ideal for any work that requires head and hearing protection. Their durable construction withstands rough environments and the slim design reduces the risk of snagging in branches or confined areas.

Featuring 3 wearing positions, you can park the earmuffs on the rear of the helmet when not in use, put them in stand-by position slightly off the ears, and push them inwards into working position covering the ears.
