Navy is the color that does the most work in a men’s wardrobe without ever asking for credit, and a cardigan is the silhouette most men still haven’t figured out how to wear without looking like they’ve retired early. The ones that go wrong are either too preppy, too shapeless, or cut in a fabric that pills after three wears and bags at the elbows by Christmas. The ones we’ve pulled together here avoid all of that. We were looking specifically for weight, structure at the shoulder, and a button stance that works whether you’re wearing it open over a tee or closed over a shirt. Nothing in here reads as an afterthought. Nothing looks like it came from a supermarket seasonal rack. A navy cardigan done right sits somewhere between a light jacket and a sweater, filling a gap in the wardrobe that most men don’t even notice until they own one. These fill it well.
