Help in identification

[draganns]

I found few helmets with very strange liners. Helmets were repainted for movie but I never see liner like this. When some shells are used for movie comon optios for movie-makers is tup put some spunge instead liner. Those liners look like fabric made but strange thing is green color inside liner. Can somebody help me in identification.

Thanks
