What do you get when you cross a field jacket with a classic button-up? The Canvas Shirt Jacket — that’s what. The 9.5 ounce canvas feels sturdy, yet remains flexible courtesy of a hint of spandex. It’s got two handy hip pockets for stowing odds and ends. And it’s styled to go just about anywhere, from a day at the office to a night out. No doubt about it: this is a top-end top layer.
