Every guy should consider owning a peacoat, especially if you’re not the type to buy new outerwear every year. Perennially stylish and particularly grime-resistant in grey, this Kai-Aakmann peacoat is the perfect choice from Oak. While it has plenty of detail to remain interesting, this grey peacoat is classic enough to slide through multiple years and seasons. Thick, in 100% wool. [$292 at oak]
