This is for all of our canvas based jackets (not leather)

We take two layers of the canvas and sew them together before putting the jacket together.  This is available on any color canvas jacket.Only add one of these options -fleece/double/or thickness upgrade.It's too thick for more than one of these options. Please choose one or the other.

Standard jackets are 10 oz. canvas.
