Forged on the rugged coastline of Ventura, California, Iron & Resin has spent well over a decade carving out a distinct niche where surf heritage, motorcycle culture, and blue-collar utility meet. Their design ethos has never been about chasing fleeting runway trends; it is about building honest, indestructible menswear designed to be worn in, not out.

For their latest Autumn collection, the West Coast outfit has delivered a masterclass in transitional layering, pairing heavy-gauge duck canvas and waxed fabrics with shearling linings, jacquard cotton, and Sorona insulation. If you are looking to bolster your cold-weather wardrobe with gear that actually stands up to serious punishment, here are 8 of the best new menswear pieces from Iron & Resin this fall.
Basin Jacket V2

A triumphant return for one of the brand’s most celebrated outerwear silhouettes, the Basin Jacket V2 (£367) has been upgraded with an authentic goat suede yoke for added visual grit and tactile contrast. Constructed with a heavy-duty 4.5oz waxed cotton canvas exterior and insulated with 3oz eco-friendly polyester fill, it shrugs off wind and drizzle with ease while keeping the cold at bay. Finished with a plush shearling collar lining, a heavy-duty Talon front zip guarded by a brushed silver snap placket, and a trio of practical interior pockets, it is a luxurious yet thoroughly hard-wearing investment coat built for the long haul.
Great Plains Cardigan

Cardigans often err on the delicate side, but the Great Plains Cardigan (£260) is engineered like a piece of heavy-duty outerwear. As the heftiest knit in Iron & Resin’s entire lineup, it combines an ultra-dense 80% wool and 20% nylon knit exterior with a thick, insulating polyester sherpa lining that runs throughout the interior. Swapping fussy traditional buttons for an industrial metal zip closure and featuring deep front hand pockets to shelter cold hands, it is the ultimate cold-morning layer for days when a standard wool jumper simply won’t cut it.
Wyatt Shirt

Nothing captures timeless Western workwear quite like a properly built flannel, and the Wyatt Shirt (£92) executes the formula to perfection. Crafted from a substantial, brushed cotton flannel that feels soft against the skin while retaining serious structural durability, this shirt is detailed with classic Western-styled front and back pointed yokes. Finished with authentic pearl snap buttons down the front placket, dual snap chest pockets, and buttoned cuffs, it serves as a versatile daily driver whether worn solo or unbuttoned over a heavy graphic tee.
Dyer Jacket

Taking the timeless aesthetic of a military flight jacket and supercharging it with modern thermal technology, the Dyer Jacket (£122) is an indispensable lightweight puffer for active autumn mornings. Built with a tough 100% nylon shell, the jacket is stuffed with eco-friendly Sorona Aura insulation to deliver superior warmth-to-weight performance without unnecessary bulk. Thick ribbed knit along the collar, cuffs, and hem seals in vital body heat, while zipped hand pockets and an antique silver front zip make it a streamlined companion for brisk beach walks and morning motorbike commutes.
Masterson Shirt

Built specifically to take a beating and look better with every scuff and scrape, the Masterson Shirt (£115) straddles the boundary between a heavy button-down and a lightweight utility jacket. Woven from a substantial 10.6oz twisted-yarn jacquard cotton in a deep black colourway, this heavyweight overshirt has an incredible tactile texture that breaks in beautifully over time. Outfitted with durable metal buttons, twin flap chest pockets, and dual welt hand-warmer pockets, it is purpose-built for chopping firewood, workshop wrenching, or casual autumn pub stops.
Sanjon Jacket

Classic American workwear done right, the Sanjon Jacket (£176) is a quintessential duck canvas chore coat crafted for effortless transitional styling. Built from a bulletproof 12oz 100% cotton duck canvas in an autumnal Cognac hue, it features a warm, custom buffalo check flannel lining that keeps your core comfortable when temperatures plummet. A contrasting black corduroy collar elevates the silhouette, while industrial Talon-zipped chest and hand pockets ensure your daily essentials stay secure on the go.
Anvil Work Pant

Formerly known as the Union Work Pant, the Anvil Work Pant (£107) has earned a cult following among tradesmen, mechanics, and outdoor enthusiasts for good reason. Cut from an unrelenting 14oz 100% cotton duck canvas, these trousers feature double-layered front thigh-to-knee panels and reinforced rear ankle cuffs to prevent fraying from heavy boot friction. With double-needle felled seams, custom branded rivets at high-stress points, a dedicated right-leg utility pocket, and an integrated D-ring key clip, they are an undisputed heavy-duty workhorse for your lower half.
Rogue Vest

When you need core insulation without sacrificing arm mobility on the trail or behind the handlebars, the Rogue Vest (£89) is the ideal mid-layer solution. Featuring a durable 100% nylon shell packed with 100 GSM quilted poly-fill insulation, it provides impressive warmth while remaining compressible enough to stash into a daypack when the midday sun emerges. The dual-closure front pairs a smooth-gliding zip with heavy-duty metal shank buttons, while top-fold snap pockets and cosy side-seam hand pockets round out an exceptionally versatile, packable layer.
