This is an authentic US Military new old stock nuclear biological chemical hood M6A2 for the US M17 gas mask. This is the gas mask with the internal triangular cheek plate filters.  OD green color only.

Will also fit the Czechoslovakia M10M gas mask which is a copy of the US M17.

Has a front zipper, multiple draw strings and velcro attachment points.

This hood will not properly fit any other gas mask not listed above! 

Still sealed in either a paper or plastic wrapper as shown in one of the pictures.

One picture shows the hood installed on an M17 for illustrative purposes but mask is NOT included.
