Designed to deliver an exceptional fit, this half-face respirator is molded from pure silicone material for rugged durability and superior comfort. A textured, nonslip face seal prevents the mask from moving, maintaining a proper fit during use. The extra-large sealing surface fits snugly over a wide variety of facial features, while the ultra-soft nose bridge reduces pressure points at a key fitting area. 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 (masks available with or without cartridges included). Availabe sizes: S, M and L.
