Loadout Master FAST Helmet Face Protector
RSOV.com have this FAST Helmet Face Protector from Loadout Master, though we consider it more to be more a side/ear protector as it still leaves a good portion exposed. What's neat about this is that it allows for radio headsets to be worn by the player whilst it's attached to the FAST Helmet. It costs just US$9.99 and available in black, tan, ACU, and OD colours. Don't forget to add eye protection when you wear this.
