Answers.Text: I will say that not only are they mostly decorative today but if you want a usable stein+lid that you should make sure the lid will open enough to get out of your way before you buy the stein.  I was gifted one and it is purely a decorative mug at this point due to the lid being in the way.

  Today they're largely just traditional. However, originally they helped:
  
  1. To keep the beer cool by preventing airflow from above.
  2. To keep insects and other contaminants out.
  3. To prevent spillage while cheers-ing and generally carousing.
