Aussie George Finch invented the down jacket, but new artificial polar bear fur is better:
Down jackets have had a 100-year heyday in global fashion thanks to Australian mountaineer George Finch, according to Snowshoe Magazine. In 1922, Finch was the laughingstock of his mountaineering circle, showing up to climbs wearing strange pillowy garb made of feathers and hot air balloon fabric while his friends continued to dress in tweed. He soon silenced their taunting, however, climbing higher than anyone else had ever climbed.
The group knitted a sweater out of the revamped aerogel fiber and tested its insulation against a down jacket, a wool sweater and a long-sleeved cotton top.
While the “polar bear” aerogel sweater was only one-fifth as thick as the down jacket, it had the best insulation of all four fabrics, according to the study.
