Call it what you will—an overshirt, shirt jacket or shacket—now is its time to shine. I know we are approaching spring, but it's still plenty chilly out, right? Which means that between now and the arrival of true warm weather, we exist in the sweet spot for lightweight outerwear. You know, that annoying and unpredictable phase of cool mornings, warm afternoons (with the chance of showers), followed by an evening chill. Embrace the shirt jacket and you'll be set all day long.

Because the temperatures fluctuate so much this time of year, you want something that can be light enough to throw over anything, yet substantial enough to provide some actual insulation. It's also a ruggedly handsome piece that's easy to pull on with everything from chinos and jeans to some pleated wide-leg trousers. Hell, this even works with shorts come summertime.

There are tons of affordable and investment-worthy overshirts in a range of weights, fits and fabrics. You need to decide how cool or warm you run personally, to decide which one would suit you best. We've rounded up some stylish options that can keep you warm and looking cool while in the office or layered for those evening strolls.
