I think there comes a point where opinions on the look of jackets vs. shirt have to be tossed out the window and the function has to be taken into account. Most varsity officials in my state have a jacket in their game bag.

I think jackets are appropriate for hard rain, freezing temperatures, and snow. I find that adding and subtracting layers as conditions vary is easier to accomplish with a jacket. I've been part of games where UA Cold Gear and a treated long sleeve shirt will not do the job. A jacket allows me to throw some polar fleece into the mix which can really make things comfy on those brutal days.

I have to add that I have cause to use my jacket once every two years. lol
