The PerCap® from Howard Leight is a unique folding banded set of earplugs that can be worn under-the-chin, over-the-head and behind-the-neck. A semi-aural protector, PerCap’s soft polyurethane ear pods seal the opening of the ear canal and offer lower attenuation, making them ideal for workers exposed to low levels of hazardous noise.
