Poseidon Atmosphere Full Face Mask w/ Xstream Deep 1st Stage Regulator

Meet Atmosphere—the full-face mask designed for comfort, communication, and a secure fit.  

• The face seal is "cushion type," with a convex reflective surface for excellent comfort and seal, a technology originally developed for RAF fighter pilots.
• Visor clamps are curved to give a sufficient squeeze over the entire visor, ensuring a leak-tight fit.
• Inhaled gas is directed to flush the visor for effective demisting.
• The mask has a large panoramic visor, giving an extremely wide field of view optically corrected for distortion-free vision. All curved surfaces and sides of the visor are frosted to avoid distortion and reflection.
• The visor is covered with a white protection film used to protect the optical surface when the mask is not in use.
• Head harness buckles are made of sturdy plastics and installed into the mask to withstand a pull load of >300 N.
• The inner part of the mask is equipped with a simple internal device to close the nasal passages for underwater equalization.
