For crisp mornings and cool nights, for falling snow, and for changing seasons — a shirt jacket. It’s a staple that can stand alone as a light top layer, or function as a stylish mid-layer beneath a heavier coat when winter arrives. Typically cut from either corduroy, flannel, fleece, twill or wool, this style — also known as an overshirt — blends the shape of a basic shirt and the sensibility of something far more substantial.
What Is a Shirt Jacket?
A shirt jacket resembles your usual shirt but feels more substantial, offering more warmth when the weather calls for it. Truly! It's that simple. But how each shirt jacket delivers the extra warmth differs: Some opt for quilting and down, while others are simply heavier and made from wool. There are oversized options and tailored-fitting ones, plus ones that lean a little bit harder into outerwear aesthetics.
Also, to clear up the common shirt jacket, shacket, overshirt debate: They're all the same. A shirt jacket is literally what the name implies, while a shacket is just those two words put together. An overshirt achieves the same end goal, but with perhaps a slightly slimmer frame.
How to Pick the Right One
You shouldn't expect your shirt jacket to sub seamlessly in place for a heavier parka. Never. But you rightfully should expect to be able to wear it and it only in the tail end of winter or the beginnings of fall. If you opt for a lighter one — meaning one that's basically a shirt but called a shirt jacket — you could get away with layering it in the warmer months (when the evenings, at a crisp 60, feel cool).
Steer clear of super insulated ones because at that point you're better off upgrading to something more substantial. The shirt silhouette doesn't prove as flattering when puffed to its limits. Just get a puffer jacket. I recommend picking something flashier than your normal shirt, by way of texture, color or pattern. Save the stale blues and crisp whites for your Oxfords and button-downs.

- Best Upgrade Shirt Jacket: Wax London Whiting Shirt
- Standard Cloth Piled Fleece Shirt Jacket
- Todd Snyder x L.L. Bean Shirt Jacket
- Flint and Tinder Quilted Waxed Shirt Jacket

Made from organic cotton heavyweight will, this shirt is sturdy, soft and breathable. It has two button-flap chest pockets and natural nut buttons. Plus, if heather grey doesn't hit the spot, this style comes in over a dozen colors. It's a classic silhouette Outerknown will never quit making.
Available in five colors, Everlane's 8 oz cotton twill overshirt proves two times heavier than their standard cotton Oxford. Two flap pockets add texture to the front and both standard length and cuffs skew classic.
Wax London makes its popular Whiting Shirt in many, many different colors. This is the classic Marine Beatnik option, a mix of cream and navy recycled, French-made fibers. It takes cues from classic flannel shirts but proves far heftier.
Shirt jackets combine the best features from both regular shirts and more substantial jackets. Case in point? This Piled Fleece Shirt Jacket from Standard Cloth. It comes with a high-pile exterior and a flat inside so that it's still flattering. The texture promises warmth, while the style screams gorp/normcore. And you're not limited to this single hue; you can choose from six different colors.
From Todd Snyder's second collab with L.L. Bean, this wool shirt jacket balances the weight of a coat with the softness of a fall flannel.
Like I said, it shouldn't be an expectation that your shirt jacket comes waterproof. However, Flint and Tinder's made your ask a reality with its Quilted Waxed Shirt Jacket. Warmth is afforded by the quilting while rain is deterred by the waxed canvas. Plus, this style comes in six different colors.
Percival might be the best looking in this bunch (in my opinion). It's just pretty expensive for an overshirt. Sure, there's inherent versatility embedded in the style — you can wear it in place of a blazer, with a T-shirt underneath, as a layer in winter, as a standalone jacket with a sweater stuffed inside — but it's still a standard shirt, upgraded. But upgraded it is: It's made in London from Italian wool.
Like a blazer, some shirt jackets provide little warmth but serve as a top layer to make you look more put together. That's the intent with POP Trading's overshirt. It has a zip front — a departure from most dress shirts — and is cut from sturdy cord.
If you really want your shirt jacket to do double duty as serious outerwear, opt for an iteration like J.Crew's Eco Nordic option. It has a recycled polyester shell with PrimaLoft Black Eco down, a lightweight insulation made from upcycled plastic bottles. It could stand in for a mid-weight puffer while giving you shape of a traditional shirt.
Remember Best Made? Maybe? Well they were acquired by Duluth in 2020, and the brand's back with most of its major highlights intact. They still make their signature beanies, and this wool flannel overshirt is a take on one of the label's earliest designs. It's made from wool-blend flannel with a zip front and two chest pockets. Pick from this dark blue or a bright red.
Prana's overshirt kind of has cardigan vibes. What's that mean? Well, it's in how it hangs — sort of unstructured over the shoulders and softly down the body. It's made from Polartec Thermal Pro fleece, though, so it will prove far warmer than your standard shirt.
A kind of quasi chore coat, Bonobos' The Knit Shacket has bucket pockets at each hip, a button-up front and a jacket collar more typical to a jacket than an Oxford. It's softly knit like a sweatshirt but has the structural components of a classier top.
