Is 20 degress at altitude "colder" than 20 at sea level?
Is it harder to stay warm at altitude because the air is less dense, meaning fewer air molecules to retain heat, than if one was at sea level? So while the temp gauge may say 20 in both circumstances, if you're at 10K feet it will be much harder to stay warm, right?
Just wondering if that is correct or not? NOTE: The remainder of this post can be read by logging in. For free PBF membership click here

I found on another website that there is a decrease in thermal insulation the higher you go. I thin NOTE: The remainder of this post can be read by logging in. For free PBF membership click here

I'm mostly guessing here, but I think the biggest difference in warmth you will feel at altitude is NOTE: The remainder of this post can be read by logging in. For free PBF membership click here
