Insulation…
Clothing doesn’t “heat” you as a furnace does.
It insulates you to hold in the heat your body produces.
Clothing that traps dry air provides the best insulation.

Head: Up to 65% of heat loss can be from the head. “Put a hat on to keep your feet warm.”
Neck: Wear a scarf or (better) a hood.
Wrist: Extended jacket cuffs, gloves, or wristlets cut from an old pair of socks.
Hands: Gloves or mittens. Mittens are warmer, but offer no dexterity. Best combination - thin gloves inside heavy mittens.

FootwearRubber bottom, leather top boots with wool felt liners.
Nylon snowmobile boots with felt liners.
Rubber boots with built-in foam insulation.
Nylon gaiters
Leather boots should be treated with “snowseal” or similar dressing to keep them water resistant.
Boots must have room for whatever winter socks you plan to wear, plus room to wiggle your toes.
Don’t cut off circulation!
