I thank you for your concern. I don't know if you've served yourself but I did two years in the Belarusian armed forces and when you're covered in a lot of equipment covers of all sorts most definitely do help, even if they do add weight and more friction to give some more heat of their own. This is a magical land with magic affecting every variable along with being one by itself. I also suggest you read more of the sheet for context. But again, thank you for the thoughts.
