The puffer jacket is that rarest of things: a nineties fashion staple with real practical benefits. These padded wonders are capable of locking in heat in even the iciest of conditions, making them the first choice not just for hip-hop stars, but polar explorers and mountaineers too. And there’s another benefit: the best men’s puffer jackets have good looks on their side as well, something which hasn’t gone unnoticed by designers. In recent seasons everyone has marched puffers down the runway. And as a result, there’s been a noticeable shift in their popularity.
