The revolutionary 3M™ Speedglas™ Helmet 9000 features patented aerodynamic exhaust vents that help to remove exhaled air. Welders experience lower humidity , less heat and reduced "stuffiness".
The welder's natural breathing action directs the exhaust airflow; no moving parts are involved. Extremely comfortable, weighing only 17.4 ounces (including filter) and has excellent balance.
