At less than 13 ounces, the Moldex 9000 Series respirator is ultra-lightweight. Features an extra-wide viewing lens, with an exclusive over-molded flange design eliminating the traditional clamping frame found on most other face pieces. A convenient ratchet fastening strap system and the stand-away head harness make putting the 9000 mask on and taking it off quick and easy. The strap tabs are securely molded directly to the flange for rugged use.
