Ermenegildo Zegna

Vertical wool mill; superfine worsteds

Zegna began as a fabric maker in 1910 in Trivero, in the Biella Alps of Piedmont. The label grew into one of the biggest names in global menswear, but the mill came first, and for our purposes it still comes first. What we buy is the cloth.

The operation runs vertically, from raw fibre through to finished cloth, and that control shows up exactly where a tailor notices it: consistency. Bolt after bolt arrives with the same soft, even face and the same predictable behaviour under the shears and the iron.

The setting is not incidental. Since the 1930s the house has planted more than 500,000 trees around the mill, and Oasi Zegna, the nature reserve that grew out of that work, now stretches 100 square kilometres from Trivero to the peaks above it. A mill that thinks in decades tends to weave that way too.

In the fitting room, Zegna is one of the names clients ask for most, and one of the easiest for us to recommend. The superfine worsteds drape cleanly and press sharply, and they keep doing both long after the first wear. The cloth behaves, which is most of what anyone actually wants from a suit.
