That is fascinating. I have never experienced this problem at all, texstyle! I don't mean to say I have never experienced static electricity. It happens mostly with skirts clinging to hose, or sometimes when you are wearing a hat, your hair will get some sparks. Or in bed at night with your jammies if there are a lot of competing polyesters, you might see "fireflies" under the sheets when you move. (One reason I go for cotton sheets/ PJS.)
Do you have extremely dry air?
Where I live, winter air is not excessively dry. In fact, it can be extremely damp, and oftentimes, the damp is what makes us feel cold. I live on the shore of one of the great lakes.
So while we do have some static electricity issues in winter, they are pretty mild.
I can't ever remember noticing static while wearing a puffer coat. Ever .
