Riddell Speedflex - The Zero G Plus is confirmed to fit ALL factory Riddell Speed Flex facemask styles. Ranging from an adult Extra Large size helmet down to youth small. We have had no issues fitting any of the Speedflex helmets
Riddell Speed - We have also tested on several of the Riddell Speed facemasks including the newer HS4's. We have had no issue so far with the few helmet mask combos we have tested.
Schutt F7 - We have found the visor to also work on most of the Schutt F7's. Schutt is way less consistent with their masks than Riddell is. Even the same style. For some F7 masks the visor goes straight on but at other times with the Schutt Quick Connect Facemask Clip it can take a little work to get it to fit correctly. We have made a full install video showing several ways of attaching it.
Schutt Vengeance - We have not tested on a Vengeance at this time. As we do not have access to one. We will be testing very soon. We do believe it will fit the Vengeance but it will need to be installed exactly the same as an F7 when it comes to using the Schutt Facemask quick plate.
Vicis - We have tested on the Zero 1 facemasks. We have a helmet arriving soon. We believe that the Zero G Plus will fit the Zero 1's no issue. We are waiting on a Zero 2. From the photos we have seen and based on the generic visors we have seen on them at some NCAA teams, we are confident that the Zero G Plus will fit the Vicis Zero 2. We are waiting to test and will update ASAP.
Xenith - For Xenith Helmets the Zero G Plus visor will fit, we have now added in longer clips as an accessory to all visors. We have tested the standard type masks and one of the Alien types, The Prime. The visor fits the Prime better than ANY visor we have ever used.
