  • Integrated face shield to protect against wind and debris
  • Height-adjustable shield for flexible visibility and quick adjustments
  • Padded chin strap with double-D safety lock for dependable closure
  • Side goggle traction pad to hold straps and goggles securely

Safety, standards, and serviceability
