Here’s another item for your layering arsenal. Behold…the chunky sweater.
This one from Folk is rugged enough to sub in for a blazer on a warm day—or, if you’re feeling adventurous, layer underneath one—and the checker-knit merino wool gives it a chess-player casualness that’s hard to come by otherwise.
Of course, it won’t do much against the wind, but all you’ll need for that is a raincoat or a Harrington over top. And a tie probably wouldn’t hurt.
