|5 degree Fahrenheit, 8 mph wind with Lake effect snow. That equates to a -8 windchill when walking into the wind, -2 degree windchill when walking with the wind....and feels like -30 windchill when you are sitting still.|
|I had a lot of company regarding -10 windchill|
|This is in addition to skivvies, T-shirt and jeans. The German Shepherd hair is optional.|
|Knit hat and a scarf cut from polyester fleece. The scarf addresses the weakest point in my system...my chin to my sternum.|
|Insulated "bibs" or overalls. I used to wear coveralls, i.e., one piece suits but found that the loss in flexibility and the difficulty in layering up/down outweighed the greater warmth.|
|A quilted, duck work coat. Another weak point in the system is that the knit hat wants to walk forward when I have the hood up.|
The first two things I do when I start getting warm is to drop my hood and to switch from mittens-to-gloves. Then coats and such start getting unzipped and/or removed. It is better to be cool than warm and sweaty.
Footwear is personal. There is little risk of getting wet feet when there is little snow on the ground and the air temperature is 5 F. I wore running shoes and was fine for the two hours I was outside.
Your mileage will vary depending on your size, metabolism, fat covering and sensitivity to cold.
