With this BADASS Eyeshield, dirt and opposing hands on the face are no longer an issue. Sun rays are also slightly deflected so that they no longer disturb the eyes. It is attached to the mask with two fasteners. The Eyeshield basically fits all adult helmets. It is compatible with most masks because it is also flexible to a certain extent. If you are not sure, unfortunately you have to try it, because there are so many masks on the market to be 100% affirmed for everyone.
