MUST HAVE
A friend told me about these - and after five years of 3-8 long haul (Asia/Australia from East Coast US) and dozens of transcontinental and US-Europe flights a year I would not be without them.  They last through dozens of machine washings and are comfortable even when new.  DVT is a real threat to any of us traveling for hours via air and I would not travel without a pair or two of these with me.  I've tried other brands but these are the best from the standpoint of quality and comfort.
