If I'm not mistaken, they could be to protect the sleeves from stains or possibly being crinkled. There are variations of these. I've seen some that are longer that you wear while driving to avoid getting a tan. Some are an entire frock you wear from the front and tie at the back that you use or cooking (basically a sleeved apron).
Y’all can someone tell me what are those gray things bro wears on his lower arms? Like it’s even on the cover ? What are those arm warmer looking things?
