What I wore...

Thin liner socks
chemical toe warmers
mid-weight wool socks
shoes
shoe covers
padded tights
knee warmers
craft base layer
very thin PI base layer
chemical body warmers (one front, one back - don't recommend the back one)
tyvek FedEx pouches
jersey
armwarmers
Sugoi jacket (from my team kit, not sure what model it is, but think it's just their winter jersey)
Polar buff around neck and face
Adidas thermal beanie
thin gloves
hand warmers
thick PI gloves

I was quite comfy, and shed warmers, FedEx pouches, arm and knee warmers throughout the day. Didn't put them back on after sunset, but I probably should have, as I was quite cold when I finished.
