As I embark on my -20C drive from Woodstock Ontario to Maumee Ohio, I am prepared to drive without heat to cover the distance. I have a hat, gloves and scarf but, it occurs to me jackets are counter productive. They only open from the front while insulating your back from the efficient seat heater. I thought a reverse jacket would be ideal and realized "Crap.... that's a Snuggie?" Imagine containing all that seat heat while having full use of your arms. Fantastic! If only they weren't an embarrassment.
