Dave,
I have one from gray wolf woolens in predator fall brown wool that I love, fall brown colors are very similar to asat colors. You also could ask jeff (gray wolf woolens owner) if he has any asat material kickin around to make a hat with. You could also probably buy fabric from asat (or day one) and send it to jeff.
First lite makes a brimmed beanie in asat that is similar to a radar cap, I do not have the beanie though so I can't comment on how well it works. Other First lite products I have are top notch though.
