  • Low profile design fits under most grinding and welding helmets
  • Extended field of vision
  • Large inhalation valves (quarter-sized) allows users to inhale a larger volume of air per breath
  • Exhalation valve is strategically positioned under the nostrils and in front of the mouth to ensure hot, exhaled air exits the mask immediately
  • Exhalation valve diaphragm has channels that act like a parachute to trap exhaled air and lift the diaphragm off the valve seat with very little effort which creates more space for air to exit the mask
  • Rolled sealing flange provides comfort and improves fit
  • Textured sealing area reduces risk of the mask slipping on the face
  • Enhanced harness assembly features:
    • Metal tabs at end to prevent nylon strap fraying and allowing for adjustment when wearing gloves
    • Wide nylon strap maintains elasticity longer
    • 4-point swiveling adjustments allows the mask to be adjusted to the individual features
    • Cradle suspension fits comfortably under suspension systems for hard hats, grinding and welding helmets
  • 3-position adjustment allows users to adjust cartridge to three different positions
