I played a lot of football in high school and if the temps were below 32 we had to wear sleeves (never mind that sleeves only protected to a point). We couldn't wear gloves way back when, but had to protect the arms. If what we are told about frostbite is true and skin is in danger of frostbite in like 30 seconds or something that, it seems to me that there would be a lot of frostbite going on the field and in the stands. Of course this is coming from someone who will be participating in the Hawkeye wrestling Artic Plunge this year.
