Men’s Brown B-3 RAF Aviator Double Collar Shearling Jacket - The Ultimate Arctic Shield | Full Grain Apparel

The Men’s Brown B-3 RAF Aviator Double Collar Jacket represents the absolute peak of winter protection. While the classic B-3 is famous for its single oversized collar, the Double Collar edition introduces an innovative inner shearling "stand collar" that works in tandem with the buckled outer collar. This creates a dual-layered thermal barrier, effectively sealing your neck against freezing drafts and making it the most insulated aviator in our collection.

Key Features

• Material: 100% Genuine Double-Face Sheepskin. A rugged, Mahogany Brown leather exterior is naturally bonded to a thick, Natural Cream Shearling interior. This is a "single-skin" construction, meaning the wool isn't a liner—it's part of the hide itself.

• The Double Collar System: Features a plush inner shearling collar that sits snug against the skin, and a large outer collar equipped with dual leather buckle straps. This tiered design allows for maximum heat retention and windproofing around the neck and face.

• Heritage Construction: Authentic to RAF and Airforce specs, every seam is reinforced with Dark Brown cowhide leather taping. This iconic "windowpane" design prevents the sheepskin from stretching and ensures a completely windproof seal.

• Thermal Performance: Engineered for sub-zero extremes. The dense wool fibers trap body heat to create a biological furnace, while the leather shell serves as a 100% windproof and water-resistant shield.

• Hardware: Outfitted with heavy-duty antique brass YKK zippers and industrial-grade side-waist buckles to customize the fit and lock in warmth at the hem.

• Adjustable Cuffs: Features zippered or belted cuffs that reveal the thick interior wool when rolled back, allowing you to adjust sleeve length while maintaining a thermal seal.

• Storage: Two deep, wool-lined "slash" pockets at the waist, perfectly angled for hand comfort in the harshest winter gales.

The "Double Collar" Distinction

The Elite Insulator: The primary advantage of the Double Collar B-3 is the elimination of the "chimney effect" (where heat escapes out the top of your jacket). By adding a second layer of shearling around the throat, this jacket maintains a consistent internal temperature better than any other model, making it the preferred choice for mountain climates and open-cockpit enthusiasts.

Style Inspiration

The Double Collar B-3 is a substantial, commanding garment. To balance its robust silhouette, pair it with straight-leg dark denim and rugged brown leather boots. For a classic military aesthetic, layer it over a cream cable-knit fisherman’s sweater or a heavy-duty flannel shirt.
