Depends upon what the blanket is made of. E.g., I don't think that an ordinary wool blanket would commute with one of the silvery hi-tech blankets that first responders use. Those silvery blankets *reflect* (essentially all normal) wavelengths, while a wool blanket depends upon a quiet thickness of (hopefully dry) air; the wool is merely used to keep the thickness and reduce air movement (convection). I noticed that my down sleeping bag doesn't protect me from the cold ground -- I need a separate hard foam that keeps me a certain distance from the ground. On the other hand, those silvery first responder blankets also trap moisture, so you could end up with the inner surface covered with ice -- like uninsulated windows on a winter's day.

Do blankets commute?
Not esthetically (of course), but thermally?
