I actually came up with an idea for this a while back. I remember back in the day, when editing/creating a player... You were able to have 2 sets of accessories for 1 player. There was a Grass/Turf tab so depending on the field you were on, your player would wear specific accessories.
I was hoping they would put that back in, and then add in a "Cold" tab. Have it set so the players would only wear that stuff when the game-time temperature was 45 degrees or lower.
