freeballing in the cold

so far it has gotten down to freezing temperatures in the morning and it hasn't effected my freeballing yet. since I haven't gone through a cold winter freeballing I still have my underwear on hand in case it gets to nasty out to freeball I have also purchased a few new pairs of long underwear that are very comfortably (but not as much as freeballing is) that I could wear when I have to. I do plan on wearing them at least once just to see how they feel.
