Designed to deliver an exceptional fit, this half-face respirator is molded from a custom-engineered thermoplastic blend that combines economy with function. A textured, nonslip face seal prevents the mask from moving, maintaining a proper fit during use. The rolled sealing area gently conforms to a wide variety of facial features. A strategically positioned, corrugated exhalation valve helps eliminate dead air to enhance wearer comfort. The unique Saf-Twist connection system lets you attach cartridges in three different positions to maximize compatibility with eye and face protection (cartridges sold separately). Available sizes: Small/Medium and Medium/Large.
