1st Layer:
- ID
- A wicking hat, with a brim if it's snowing or raining
- Wicking, light-weight, snug running shirt, long-sleeved if it's cold out, short-sleeved if it's cool
- Light-weight running gloves
- Light-weight running tights
- Wicking undergarments, especially important for men
- Thick, absorbent socks
- Running shoes, of course
- Moisturizer and/or sunscreen
This first layer can safely be worn alone in cool temperatures over 40 degrees Fahrenheit. Of course, it is fine to wear more if you still feel cold when you are running in the winter. Remember, however, that you should dress as if it is 20 degrees warmer than it actually feels outside because you'll warm up as you run.
2nd Layer:
- Polypropylene (Coolmax or Thermax) long-sleeved shirt and/or a light-weight windbreaker jacket
- Mittens
- heavy tights, replacing the light-weight tights from the first layer
- For the guys, insulated underwear may be worn to prevent cold-related injuries in especially sensitive areas
This second layer should start being worn when temperature drop below 40 degrees Fahrenheit. This layer of clothing, in addition to the first layer, should protect you when running in near-freezing winter weather. This layer is used to keep in warm air, but release enough air to avoid overheating.
3rd Layer:
- Balaclava or similar ski mask
- Vaseline covering all exposed skin
- Long-sleeved shirt AND windbreaker jacket (Goretex is a good option)
- Lined, waterproof mittens
- Fleece pant linings
This third layer is worn when it is below freezing and over 0 degrees Fahrenheit. I don't recommend running outside in below 0 degrees weather. This layer should be breathable and water-resistant.
