No, I guarantee that I look more streamlined, athletic and better looking if I leave the jacket OUT. I have a big belly and I'm already tucking in three layers of XXL shirts into my pants. Tucking in a jacket over a CP is like asking for ridicule before the game even starts. I get enuf of that here.
Well, what good is a jacket tucked in if it starts raining? I prefer keeping the balls warm and dry. Cold light drizzle soaking down into my pants defeats the purpose of wearing the jacket.
