Looking at some thermal under wear and really left wondering why one would choose a vest or long sleeve top?! It may seem obvious but I can't think why a long sleeve top would be better than a vest of the main purpose is to keep your core warm? Do some people feel the cold badly on their arms?
Perhaps some people don't wear them underneath other clothes?
Or maybe it's to reduce sweaty armpits?
Will my arms be warmer for having the extra length or will I just be a hot mess?
I know someone will have the answer, I'm not being facetious and the answer will help me pick what's best for me 🙂
