Hi:
Even when this question is not related to aviation technical issues, I'd like to ask to any A&P mechanic who have worked in cold weather conditions (24°F-35°F aprox) outside of a hangar, about what clothes are good to keep me warm enough to handle the cold when the job is outdoors,and at the same time is comfortable to use the tools.
Professional goals have taken me from my tropical home to one where there are well defined seasons. This is my first time that I will experience a winter season and I want to pass through it as good as I can.

Thanks,

Franklin.

First know the weather and how to take care of yourself when you are working in the cold.

Then how to dress: When working in cold weather, you need to dress in layers that will wick away moisture, insulate from the cold, and keep out the wind and rain. From head to toe and inside to outside, here is what to wear.

Use the Layering Principle

Base Layer: Wicking fabric to keep your skin dry and prevent that clammy feeling.

Insulating Layer: Fleece or wool, vest or shirt that can be added or removed depending on how cold you feel.

Windproof and Water-Resistant Outer Layer: A jacket, preferably with a hood, to keep out the elements.

The following are some websites about the cold and being in it.

That's It Good That Answer I Found That Imformation Really Useful Now I Don't Get Cold When I Go Out

I wear a sweatshirt and a thin windproof fabric jacket and the coveralls over this when working outdoors in the winter here in Canada. Though I am used to the weather more I'm sure. You really can't move freely with a heavy winter coat but some more expensive winter coats are thin but just as warm as the thick ones and can be worn under coveralls.

Suede or leather gloves (lined) are good for working with tools.

I used to work as an A&P mechanic, not any longer though.

I recommend moving somewhere where the ramp is never below 50 degrees:)
