The funnel neck is one of those details that either looks considered or looks like a costume, and the difference is almost entirely down to how the collar is constructed and what the rest of the jacket is doing. Too much volume up top and you look like you’ve borrowed something from a film set. Too little and the whole point is lost. We’ve been looking specifically at jackets where the funnel neck earns its place rather than dominates the whole thing. The kind that works over a fine knit, reads well without a scarf, and holds its shape across a full day rather than collapsing by midmorning. These sit in that territory between a smart coat and a relaxed outerwear piece, which is exactly where a lot of men’s dressing actually lives. Fabric weight matters here. So does the way the collar sits when it’s not fully zipped. These are the jackets that get both right.
