The NM-C27/Y earmuffs are designed to offer a high level of hearing protection, thanks to a solid construction and carefully selected materials. The cups and headband are made of ABS, a material that guarantees mechanical resistance and durability over time, while the PVC earpads ensure good insulation and a proper fit to the ear contours. The adjustable headband design allows for a stable fit that adapts to different sizes, maintaining uniform pressure to optimize noise attenuation. The construction is designed for continuous use, with particular attention to simplicity and robustness.
