A respiratory protective hood having an integrated, externally adjustable noseclip for occluding the nose to obstruct nasal respiration. An air-impermeable hood adapted to enclose the head of a wearer is provided. The hood has a nasal region, an ocular region and an oral region. A substantially transparent visor is sealingly integrated into the ocular region of the air-impermeable hood and adapted to permit outward vision by the wearer. A noseclip adapted to compress a wearer's nostrils together is provided thereby substantially inhibiting nasal respiration. An actuator for engaging and disengaging the noseclip from the wearer's nostrils is positioned external to a nasal access passage cut from the air-impermeable hood in the nasal region. An elastomeric air-impermeable boot securely fitted to the actuator means air-impermeably seals the nasal access passage whereby the wearer engages and disengages the noseclip to the wearer's nostrils by manipulation of the actuator.
