Electrically heated clothing (2013)
As one of the comments mentions, the best solution to cold temperatures has always been wool. As a foreigner it&#x27;s striking to me how little wool is worn here in the US.<p>It&#x27;s one of the few renewable natural fibres and a fantastic insulator. Get some merino long johns and wool sweaters and you&#x27;re good. It&#x27;s not itchy.
