100% cotton. Lightweight twill fabric. Full button fastening. Chest pocket. Interior chest pocket. Two lower pockets. Drawstring hem. Regular fit. The ADN Jacket is another slick slab of vineyard-friendly garb from Arpenteur. Its got that classic work jacket shape, but as its made out of some cotton twill of the lightweight variety, its a bit less bulky than most work jackets of this ilk. This essentially means its primed for long hours toiling in the sun, stomping grapes and what-have-you or whatever it is you spend your free time doing.
