Set this beside a navy chino and the navy goes flat. Forest Ash is AG's name for an ashy grey-green, dark enough to work as a neutral and green enough that it is not another navy or grey. In the brand's photos it sits between dark olive and charcoal. AG cuts it in a 10.2 oz cotton gabardine, a fine diagonal twill with a close, even face and a bit of weight.
AG files this under its Tailored Edit, and the Everett block is the reason it works. Slim straight and mid rise, with room through the hip and thigh and a leg that narrows a touch toward the hem. The initials are Adriano Goldschmied's, and the Everett is the block we keep pointing people to: it sits tailored without ever looking tight.
This is where we are steering our denim wall. Everett and Protege give a straight, comfortable leg that looks current without turning baggy. Sizes run by waist in inches, 29 to 42, and the inseam is 32 inches as made. We hem trousers in store, so bring them in and we will set the length once you have them on.
It is the pant for the days a jean is too casual and a dress trouser is too much. AG shows it with a charcoal work shirt and black Chelsea boots, and that is the right instinct. We would add a navy crewneck, a brown suede jacket or a tweed sport coat, and keep the shoes dark.
