You know a classic cardigan and it’s … well, fine. It’s classic for a reason. But some guys might hear the word and think stodgy unc vibes. This season’s crop of crewneck versions fixes that. The higher neckline closes the gap at the chest, so it reads cleaner and more streamlined, closer to a sweater than a grandpa knit. But it still opens up like a jacket when the room gets warm.

That’s what makes it so useful. Button it all the way and it works on its own, like a sweater with a little more structure. Leave it open over a T-shirt, tank or an oxford and it becomes a light layer. It even slips under a sport coat or overcoat without adding bulk. Look for a neckline that sits close without choking, a body that’s trim but not tight and a knit fine enough to have some drape to it.

As for what you get for your money, it mostly comes down to the yarn. An entry-level pick gets you warm, practical merino. Spend more and you get cashmere and cleaner construction. At the top end, it’s Japanese design and a fiber you won’t find everywhere. Here are the ones we’d suggest buying.
