Since Bauer patented his invention in 1939, a number of designers have experimented with similar technology. In the late '30s, the first women’s evening puffer marked a breakaway from the jacket’s practical beginnings. Fast-forward to the '80s and designer Norma Kamali unveiled her sleeping bag coat — inspired by a camping trip which ended with Kamali traipsing the great outdoors wrapped in her sleeping bag for warmth — the iconic piece is still in production to this day. That same decade, a Milanese subculture scene brought Moncler’s range of puffer jackets to the forefront. The activewear brand had been supplying skiers and mountaineers since the '50s, but it was the Italian youths of the Paninaro movement that revealed the stylish side to its designs. From Timberland to Fila, the affluent collective repurposed sports and workwear garments and gave brands such as Moncler a luxurious edge.
