Supertrooper vest material???

[Battrooper]

I want to upgrade my flight suit and vest so I have been looking at the reference photos.
Thing is I cant tell what the vest is made from.
To me it looks to be the same as the flight suit. Am I wrong? I know that most Fett vests are more of a satin type material.
What do you guys think? I would like this costume to be up to Mandalorian Merc or 501st standards.

Should be the same material as the Boba Fett vest....no reason theyd have remade the vest for Fett.
