Made of a poly-coated Tyvek material, this hood is designed and constructed in one-piece with the downtube and head suspension completely integrated. This makes it maintenance free eliminating the need for decontamination of the breathing tube or replacement parts since the entire assembly is disposed of after use. The Tyvek material is flexible, splash resistant and seals in the air flow. The hood features a large lens for increased visibility. NIOSH approved.
