We’re not entirely sure how the softest shirt jacket we tested isn’t 100% cotton. Faherty, one of the best men’s brands in the game right now, actually employed a polyester-viscose-spandex blend that has four-way stretch (a method favored by most activewear brands these days). That means this shirt has a bit more backbone, won’t shrink, and allows for a heightened range of motion than you’d normally find in a flannel button-down. But somehow, this is also just an unconscionably soft shirt. You could wear it over an undershirt, but it feels like a blanket against bare skin.

From their Bernie-inspired mitten campaign to their 10-year plan for the planet, Outerknown has lead the sustainable brand charge for years, and even better, their products are actually good. The oft-lauded Blanket Shirt is a perfect example of what sustainable clothing practices can look like — and also a perfect example of an excellent shacket. Made from 100% organic cotton, the shirt’s construction uses no harmful chemicals as to be safer for farmers and the environment, and its buttons are sourced from the fallen seeds of the tagua palm, creating an industry that safeguards South American rainforests from deforestation. It’s sturdy, warm and conscious; everything we could ask for in a top.

Shirt jackets often invite debate over nomenclature. Is it too shirty to be called a jacket? Or vice versa? Everlane doesn’t really care. The SF-based masters of basics officially call this piece an “Overshirt,” but acknowledge it could function as an “over-jacket” or “over-sweater,” too. We enjoy wearing this shirt jacket with the buttons up, as it easily pulls off a more formal look, without sacrificing the comfort you’re accustomed to from the softer layering pieces in your closet. The material is an 8 oz. heavy cotton twill (which Everlane notes is twice as heavy as its Japanese Oxford cloth), and the two front pockets give it an extra dose of character. Thanks to Everlane’s accessible pricing, this is also one of the best deals you’ll find on this list.

As if it weren’t enough that Uniqlo’s heavy shirt jacket is a mere $60, the fit of the top is bar none on this list. While it’s not the softest, nor coziest, not most breathable, it fits like a damn glove, and with its price tag, you really can’t go wrong.

Flint and Tinder makes sturdy clothes. There’s no question about it, and in case you needed proof, feast your eyes on the Quilted Waxed Shirt Jacket (or their Waxed Trucker Jackets, or 365 Chinos, or…). With a British Millerain waxed canvas shell and 100% recycled {rimaloft insulation, the shirt can easily withstand adverse and windy conditions, but with a seemed quilting and two discrete flap chest pockets, it functions just as well under a duffle coat or parka. Really, the possibilities are endless.

A shirt jacket presents a unique opportunity — as a top layer, it’s a perfect focal point for any ‘fit. If you’ve graduated to the elite school of dressing, you’ll surely appreciate the subtle swag of NYC-based Corridor’s sleek CPO; buttery-soft and decked out in intricately woven print, it’s the total package. If you dare to pair this joint with some massive pants and your favorite raglan coat, you’ll surely be the talk of the town (and splattered all over IG).

It’s no surprise that the shacket decked out in corduroy and a fleece lining won most cozy; after all, when it comes to the warmth-comfort combo, the two together just can’t be beat. This is what we like to call a “day in, day out” shirt; that is, we want to wear it, day in and day out. The traditional cut makes it even roomier, and the weight of the whole thing feels like a hug that you get to wear. How’s that for cozy?

Be they days in the woods, on the trail, at a tailgate … the running gurus at Tracksmith created a top that can do it all. Crafted from a blend of recycled wool, cotton and nylon, the New England Overshirt pays tribute to — and respects the harsh conditions of — bitter East Coast winters with a top that can handle it all, day in and day out. Billed a running layer, the overshirt is full of stretch and quick to dry, harnessing the natural warmth and wicking properties of wool. It certainly helps that, though performance-driven, the layer looks the part of a standard, albeit handsome shacket, meaning you won’t get funky looks when you’re not hitting the pavement.

If it were acceptable to swath ourselves in a comforter and wear it outside the confines of our house we would, but alas, society has not progressed to that point yet. Instead, we’ll settle for the next best thing with Public Rec’s Strech Thermal Button Down. Made with a special THERMOLITE CORE technology, the overshirt keeps you nice and snug without a bundle of extra weight, and moves with you thanks to a touch of spandex in the cotton-rayon blend. With a lounge factor this high, you’ll be hard-pressed to find a better top for easy mornings and movie nights.

It’s not every day that your regular old shirt jacket gets decked out in premium weather-resistant GORE-TEX, but Norse Projects has found a way to turn their Osa layer into something of an overshirt-rain jacket hybrid. The mesh lining, press stud closure, utility-inspired flap pocket and magnetic side pocket closures all sweeten the deal.

Lululemon’s Fleece Overshirt gets bonus points for its anti-stink gridliner weave, but let’s be honest; we were already going to cop this thing on account of its perfect casual fit.

A western-themed workshirt for those modern-day cowboys.

There’s nothing particularly revolutionary about the Universal Works Overshirt: that’s kind of the point. It’s just a handsome staple that’ll look great and wear in even better.

While this is technically just a flannel, any insulated later that plays like and overshirt is good in our books, especially one this discounted.

This feels like something Ryan Gosling would wear in The Notebook. That’s a good thing, we promise.

Is it really blue-collar stolen valor to wear a Carhartt Shirt Jac? After all, you worked hard to find that Matcha Latte.

Good for hunting, better for stuntin’.

If you’re in the market for a shirt-jacket that doubles as a full-on blanket, then you’ve come to the right place.

Easy there, Paul Bunyan.

General Admission is the coolest brand you probably don’t know yet.

Todd’s Knit Shirt Jacket is decidedly a heavy overshirt, that won’t stop us from drooling over its fine wool marl and gorgeous patterning.
