For as crucial as it is to have a stable of the best fall style essentials close at hand, there’s something to be said for mixing in the routine and tried-and-true with the brand new. Yes indeed, the usual suspects as far as your flannel shirt, your trusted selvedge jeans or your favorite pair of leather boots are reliable and essential, but what happens when a brand that you know for one category — like the coolest swim trunks — surprises you by stepping into another seasonal category? Take my good friends at Fair Harbor, for instance.

Yes, that’s right: We’re talking Fair Harbor, makers of remarkably durable and stylish men’s swim trunks, now stepping on into the world of autumn style with an array of the best flannel shirts for men.

The brand is now designed to take you a long way from the beach and the boardwalk, and this time, they’re moving inland with rugged-leaning staples like the Fair Harbor Seaside Lightweight Flannel, which uses brushed fabric and an array of classic pattern options to suitably meet the demands of the season at hand.

Organic cotton, polyester and elastane lend softness and stretch to this lightweight take on the classic flannel shirt, which uses simple details like a right chest pocket to drive the timeless nature of the flannel shirt right on home. Better still is the fact that the company is offering up this flannel in four easygoing patterns — the kind you can toss on around the bonfire or rock atop a graphic tee at your indie rock concert of choice.

Yes indeed, I’d wager the Fair Harbor Seaside Lightweight Flannel is that versatile, especially when worn with dark tan or charcoal trousers a la a few other selections on offer at Fair Harbor. It might be time to stow away your swimsuit until a seasonal getaway to warmer climes, but if you’re lucky, the Fair Harbor Seaside Lightweight Flannel delivers just enough cozy comfort and rugged layering potential in the meantime.
