The fit is way off!  I'm 5'11" 175 lbs, it is very tight for my legs.  This is not for cold climate, as advertised.  I'm in Afghanistan where it is frigid!  I think a heavy weight material would do better.  This product does not keep my legs warm.  I feel the chill through my thick jeans.  The fabric is good though.  I would use this a pajama, if the fit was right.  I hope to get a refund.
