As some of you know the chinstrap and padding that come with the IBH helmet suck, or atleast mine did. The helmet did not fit and the chinstrap was always crooked. So I replaced the chinstrap with a way better one and now it fits perfect with no movement at all. Before I could not use the NVG because the helmet would be front heavy and the chinstrap did not work, but now I can. Here are some pictures of the new chinstrap.
