The Z4 Welding/Grinding Respirator is the lightest professional flip-up available. Up to 23 percent lighter than other brands, the Z4 weighs only 1.77 pounds. Its ergonomic design evenly distributes weight to the sides of a worker’s head – eliminating top-heavy pressure points around the forehead and temples – and alleviates strains on the neck and upper back. Other features include adjustable head suspension and airflow, optical clarity, and optional padding.
