FWIW, Under Armour Cold Gear (the compression-fit style garment) helps me stay warm while deer hunting in cold weather--it wicks sweat away from my skin to the outside of the garment, thereby preventing that clammy/cold feeling during long sits on stand. I figure it'll be useful during the test because I'll probably be sweating up a storm! And sitting in what may be a cold room (according to my admission ticket) won't help matters.
I may wear a ball cap, too, to keep my body heat from escaping--IIRC, 30% of the body's heat loss is through the head.
