This coverall fits great.  i am 6'4", 325lbs, 40 waist and a 58 chest.  I have a long torso and 32" leg.  the 4xl tall fits great.  i have yet to wear it much under extreme conditions, but it is identical to my previous one and that worked great.  Material is soft, but durable.  Dark blue hides the dirt great.  Amazon has the best prices going.
