Brand new genuine Avon part # 70501-156, flexible polycarbonate outsert attaches to 50 and 53 series masks to provide additional ballistic and scratch resistance in extreme environments.  Optically correct and distortion free, the outsert can be fitted and removed by the user while the mask is being worn. Provided with outsert pouch  for storage and lens cleaning.

 

Note that this is not a replacement for the built-in clear lens of these masks, it goes over the existing built-in lens and attaches via two tabs on either side of the mask.  If your built-in lens is cracked or missing, these will not make your mask safe!
