Wind Jacket

What should I wear at about 15 degrees Fahrenheit with high wind (12,000 feet altitude in November)?

I've been living in Southern California, so I've lost my cold weather clothing sense. Could I get away with just a wind-resistant fleece jacket, a wool sweater, a shirt, and an undershirt instead of having to get a really heavy parka?

These are some things you can do to stay warm. Sorry the list is so long, I just wanted to give you alot of options to choose from in case you cant or dont want to do one of the following:

LAYERS

Dressing in Layers
Next to the skin: Your base layer should wick sweat away from your body to keep your skin dry. Cotton should not be used - save your t-shirts for other purposes. Good long underwear pieces are appropriate made from fabrics such as Thermion, polypropylene, Thermax, Thinsulate, and silk.

Insulating layer: This layer will keep you warm and can be shed once you warm up. Wool, fleece, pile, down in a jacket, shirt or vest.

Outer layer: To protect you from the elements, a windproof and water resistant jacket. It should be worn loosely.
Top Picks for Waterproof Jackets

Pants: If the weather is frigid, long underwear bottoms or tights underneath another pair of pants will keep you warm. Cotton and denim should be avoided. Running pants or running tights made of synthetics that wick moisture will keep you more comfortable in rain and snow.

A Change of Clothes: If your walking route is away from home, bring along a set of warm and dry clothes to slip into immediately after walking to keep from getting chilled by wet walking clothes.

Accessories
Hat: A hat is essential to keeping your body heat from escaping, as well as shedding rain. A polar fleece hat with ear covering is my ideal winter headgear.
Earband: For those whose ears get cold, earbands are the answer.
Top Picks for Hats and Ear Warmers
Gloves or mittens: Mittens will keep your hands the warmest as the fingers work together to build up warmth. Look for windproof mittens.

Water bottle: You need water in winter as much as in summer, and drinking fountains may be turned off. Bring water along to stay hydrated.

Scarf, neck gaiter, ski mask: Having a scarf or similar item along to wrap around your neck when the wind turns brutal can save your walking comfort.

Sunscreen and lip protector: The earth is closer to the sun in December - February, protect your skin. Lips and face can chap without protection.

Umbrella: These are known to prevent rain when carried along on your walk. Buy a very lightweight, collapsible umbrella to carry along.

Happy Feet
Waterproof shoes or boots: If your walking is wet or snowy, invest in a pair of waterproof walking or hiking shoes. Many companies including Nike and New Balance have lightweight styles to keep you dry. Coating shoes with a water repellent fabric treatments is another option. Compare Prices
Traction: Don't wear slick soled shoes if there will be wet or snowy pavement. For icy conditions, see Stabilicers, YakTrax or Ice Walker slip-on cleats.

Socks: Switch to heavier socks or wear two pairs for more insulation. Test your socks with your chosen shoes to make sure there is still room for your toes to wiggle.
