Hearing protection Kask S1C in protection class 1 for mounting on a protective helmet. Intended use is in light industry, construction, work with garden machines and smaller hand tools. The covers have three positions: Use - standby (which means a position a few centimetres from the ear that makes it easy to communicate) and folded up (backwards on the helmet when you do not need protection). Narrow profile for smooth work in tight spaces. Soft and comfortable earmuffs for comfortable wearing during long work shifts.
