Sample 1:

Jacket twill is similar to later issue and arid versions.

Jacket has same cut as arid version.


Pattern shapes are different than shapes on arid season and later, standard version (arid and later have the same shapes):


Sample 2:

Pants twill is rougher, more rigid denim.  Possibly similar to denim battledress overall material.  Ink appears to be sitting on surface like paint, not soaked in; could be why these have a tendency to fade translucently.
