Go find yourself a tarp with a reflective side on it, pitch it at an angle and drape some fire resistant plastic in front and close the ends.
Hopefully all fire retardant.
I have seen one of those tarps in a shug youtube so it is someone here that owns it.
I never have been able to find one.
Problem is you wont have a debris lean to shelter behind you to hold any heat, so once the fire dies down a bit it would cool off quick.
A top down fire might work well for this application.
