Re: Temperature control.

 I actually love their clothes (for women). The scarf is nice too. Not sure if it's viable technology - wonder (again) what Hv thinks about FIR clothing.

Never tried them and not my style.  I have used aluminized sock and glove liners though when I was riding my bicycle back East in the winter once.  Got to admit they worked pretty well until it started getting below zero Fahrenheit.  That’s when I wish I had neoprene liners to go over the liners.  Instead I had to rely on empty bread bags to cover my feet and hands to keep them from freezing.
