Wondering if the reflective lining of my winter jacket that keeps me warm also reflects microwave radiation

I have a light weight jacket from Columbia Brand that has this silver lining of dots. It works great and wondering if it also serves in protection from radiation in our environment from technology. Is it the same silver that I use to shield my walls?

GOOD, I'M SATISFIED

It is possible that this coating or layer is a reflective/conductive layer.  If it is truly designed to reflect radiant heat, then it should also have an RF reflection quality as well.  The only way to know is to test it.  Try with an HF35C or Acoustimeter.  Place a radiation source (WiFi router, cordless phone, etc) and put the coat close to it or over it.  See if it is lower with the coat than without the coat :)
