Grey is doing a lot of quiet work in most men’s wardrobes and the turtleneck might be where it earns its keep most effectively. Under a suit jacket it replaces the shirt and tie without looking like you forgot to dress properly. On its own with trousers it has a considered, pulled together quality that a crewneck rarely achieves. The problem is that most turtlenecks fail on fit. Too loose and the neck collapses. Too tight and you spend the day aware of your own throat. The roll needs enough structure to sit well without being stuffed. We’ve also been paying attention to fabric weight here because a turtleneck that pills after three wears is not a wardrobe investment, it’s just a disappointment. Merino is the benchmark. Cashmere blends are worth the stretch if you find the right one. Grey specifically because it works with navy, brown, black, and olive without requiring any thought. These are the ones that actually deliver.
