Synthetic fill has had a credibility problem in menswear for years and most of it has been deserved. Boxy silhouettes, cheap sheen on the shell fabric, quilting that puckers after two washes. The kind of jacket that says you bought it because it was warm and stopped thinking there. But the category has genuinely moved on, and there are now synthetic puffers that hold a proper shape, use fabrics that don’t catch the light like a survival blanket, and sit well over a midlayer without making you look like a sleeping bag with legs.

We’ve been focused on options that work in town as much as on a trail. Cleaner baffling, better proportions, colours that sit in a wardrobe rather than fighting with everything else in it. Synthetic fill also performs better than down in wet conditions, which in a British winter is not a minor consideration.

These are the ones that are actually worth wearing.
