More protection The 3M™ Speedglas™ Extended Coverage Accessories can help protect areas of the head and neck not covered by standard 3M™ Speedglas™ protective equipment during heavy welding and grinding operations. Tough construction Extended Coverage Accessories are made with leather or durable, flame-retardant fabric for added protection during dangerous jobs. Adaptable coverage Extended neck, ear and head covers drape over the normally exposed parts of the head and neck to help provide more comprehensive coverage, integrating with the 3M™ Speedglas™ Welding Helmets.
