SEASECashmere Baseball Cap

According to menswear writer Rob Nowill, there's a "spectrum of acceptability" when it comes to caps. "The best have unobtrusive branding and come in muted tones, " he says. Soft and unstructured, Sease's style is one you can wear with both smart and casual outfits. It's made from navy cashmere in a classic five-panel shape.
