Trouser Material?

[Thrawndike Bar]

I am planning on making my own trousers.  What material should I use?

Update: 

Also, I've seen black and light grey mesh in the underarms of the shoretrooper under shirt.  Which is the accurate color?

Canvas or duck cloth are the most common

We have an example of the undershirt here:
