SleekHeat™ Long John Bottoms

Long John Bottoms

Even the warmest coat is only good for covering half a man. That’s where our Long John Bottoms come in; because your bottom half gets cold just like the rest of you. Our lightweight warm fabric is bulk-free underneath your pants and the SleekHeat™ technology makes sure your legs stand up to the cold.
