Tyvek® Double Bib, Pharmaceutical, Maintenance Free Hood

Our Tyvek® hood has a patented breathing tube integrated directly into the hood. The tube is splash-resistant and entirely disposable. Although made flexible for on-the-job performance, the multi-layer foam tubing material prevents downtubes from being crushed or twisted, with the tube’s foam layers providing a sound-dampening system both unique and made in accordance with stringent NIOSH requirements.

This hood is engineered without head harness for freedom of movement and comfort. Hook and loop underarm straps keep the hood from rising. 8″ x 14″ viewing window offers an extensive field of vision and aptly accommodates workers with beards or goggles. The hood can be used with either an Allegro Flow Control Valve, Allegro Personal Air Cooler, or an Allegro Air Temperature Controller. Constructed from poly-coated Tyvek®, this double-bib hood offers greater protection for workers. Inner bib tucks into garments, allowing air to flow down across the body for a cooling effect. NIOSH approved.
