The granddaddy of the “puffer” jacket, Moncler has been making down coats since 1954. First coveted by French mountain climbers for subzero expeditions, the jackets now enjoy a substantial sea-level following. That devotion is thanks in part to the company’s latest designers: Giambattista Valli and Thom Browne, who are responsible for, respectively, the Gamme Rouge and Gamme Bleu collections. Valli feminized the women’s Rouge coats with cinched waists, high collars, and an all-white palette; and Browne brought his tailoring sensibility to the men’s Bleu by way of plaids, pinstripes, charcoal gray flannel, and navy corduroy. Further proof of Moncler’s widespread appeal can be found in its newest store. While most of the label’s boutiques are nestled in ski towns—Aspen, Chamonix, Saint Moritz—the shop that opened in September is located at the epicenter of fashion: New York’s SoHo.
