I was checking out the following website (BOSS Officials
http://www.sdboss.com) after reading the thread about the assualt case. Anyways, I saw where they issue a navy (pre-game) jacket.
The manual states you can wear either navy or black, but you have to match. I would guess black is the preferred color for a pre-game jacket -- as it is in my area.
Does anyone own a navy pre-game jacket and have you ever used it?
