--First Layers: Snug short-sleeve or sleeveless shirt made of tech fabric, like Capilene. Wicks moisture from your trunk without adding bulk to your arms.
--Second Layer: Turtleneck. The real deal, not a mock.
--Third Layer: Quarter-zip or half-zip pullover or a medium-weight down vest. Stay away from lots of pockets and zippers. You're not going fly-fishing.
--Fourth Layer: Windproof jacket. Hopefully it can spend some time in your bag.
--Bottom: Long underwear with windproof pants. No regular underwear. You don't need any extra commotion down there.
--Paws: Mittens between shots is a must. Double up your socks, but if you can't wiggle your toes, cut foot beds from two sheets of newspaper instead. There's usually a spare paper in the locker room, and dead trees are surprisingly insulating.
--Noggin: A wool or fleece winter hat. Triple wagers against anyone wearing a baseball cap.
