A man can never have enough sturdy, dependable menswear at his disposal, especially for frigid winter days and nights, and that’s where I find Filson gear and menswear continues to come in mighty handy, season after season, year after year.

The legendary Pacific Northwest heritage brand has been a foundational part of my wardrobe for years now, making some of the best waxed outerwear, thermals, denim and yes, one of the best shirt jackets for men.

As temperatures continue to plummet, and as I continue to put gear to the test for this Brooklyn style blog, I continually reach for Filson — perhaps you’re in the same boat? And with the drop of the new Filson Spring 2025 Collection, it’s time once again to see what’s in store from this legendary company.

The new Filson Heathered Wool Jac-Shirt isn’t quite all that new, in fact — or rather, it’s an update in term of color and fabrication to the iconic Filson line of Jac-Shirts, which are burly, thick and utterly incredible in terms of winter warmth, at least in my experience. As Filson tells it, the Jac-Shirt “has provided versatile warmth for nearly five decades,” and it’s a sentiment I agree with wholeheartedly.

This edition of the Filson Heathered Wool Jac-Shirt is made from a warm wool blend for stretch and the right amount of insulation.

And in matters of style points, it’s the Blue Heather variation of this particular Filson Heathered Wool Jac-Shirt that puts it a cut above the rest — that shade of blue almost gives it a ruggedly casual appeal, if you’re looking for something to layer over a white Oxford shirt with tobacco-hued chinos, for instance. But of course, the Filson Heathered Wool Jac-Shirt is at its best when paired with a thermal henley and canvas work pants on exceptionally brisk mornings.

The straight hem offers slightly more coverage than a traditional shirt, while front-button flap pockets offer crucial everyday carry storage space. And since this is Filson we’re talking about here, know that the brand delivers plenty of sizes and a limited lifetime guarantee on the Filson Heathered Wool Jac-Shirt.

Beyond that, this durable shirt jacket should provide plenty of room to layer over your favorite knitwear essentials — can you ask for much more from one of the best men’s shirt jackets? In my book, the Filson Heathered Wool Jac-Shirt is a certified winter style winner.
