Deeply offset, pliable headband fits head contours comfortably. Overhead band with multiple adjustments helps position the glassholder for the best view of the weld and a comfortable working position. Exclusive "free-floating" arms balance and stabilize the helmet while minimizing pressure points. Strip-proof ratchet head size adjustment provides small increment sizing. Performs well in hot or cold, is unaffected by age, does not crack or break. In models where free-floating arms are impractical, unique mounting brackets are used.
