How to stay warm during a football game?

I have a game tomorrow so I have no time to buy a hand warmer, I wear underarmour and sleeves and gloves. But how do I stay warm? I have those hand warmers where you just open it and they warm up but i dont know where to put them while I'm playing! ! I'm never on the bench cuz its football at a boys and girls club so you play offense and defense. I really need help cuz its Chicago weather! Thank You!How to stay warm during a football game?Well, usually i bring a seat warmer to games. Try to find them at your local mall in a nfl shop and they will know what you are talking about. Blankets and big coat are the only other thing to do. I hope you enjoy the game (im predicting that you guys are going to win)
