“I think I saw more Packers in long sleeves than Niners! Vince Lombardi would never have approved of that!!!”
Under Armor makes some incredible tight fitting shirts and underpants that are labeled Cold Gear when you are in the cold or Heat Gear when you are in extreme heat.
I combine them with a Simms undergarment, and they can keep the cold out. You need a good cap or ski mask type to keep your body heat from escaping out your scalp.
Yeah? Well Joe Namath wore pantyhose to keep him warm and that’s a fact!!!
