Vitale Barberis Canonico’s “Revenge” Super 150s is the most luxurious wool suiting fabric J. Hilburn offers. Its number denotes the fineness of its individual fibers — the higher the number, the narrower the fiber. This translates into a soft, smooth material that’s perfect for a special-occasion suit. At first glance, this material appears to be solid navy, but closer inspection reveals subtle tonal stripes. This fabric is available as a jacket, trousers, or vest.
