The Harrington has been earning its place in men’s wardrobes since the 1950s and the zip version is arguably the most useful iteration of it. No buttons to fumble with, cleaner lines through the chest, and it sits better under a heavier coat when the temperature actually drops. The silhouette is trim without being restrictive, which means it works over a shirt as easily as it works over a lightweight knit. What we’ve been particular about here is the quality of the zip hardware, the weight of the outer fabric, and whether the tartan lining is an afterthought or part of what makes the jacket worth owning. A cheap Harrington looks fine hanging up and lets you down the moment you put it on. The ones we’ve selected hold their shape, sit properly at the collar, and have that slightly considered quality that stops an outfit looking like it just happened. These are the ones worth knowing about.
