Sleeves are wider on the 'Raiders' version of the jacket, of course depending on the size of jacket you've got they could be wider. I prefer the wider sleeves, especially if you ever layer the jacket with more than just a shirt.
If you want skinner tapered, and more screen accurate sleeves, you should order the 'Hero' version of the Raiders. Personally speaking I need to size up on the Hero jacket just for more comfortable arm sleeves. Of course arm holes are about an inch smaller on the hero as well.
