Francis B-3 Leather Bomber Jacket: The Midnight Aviator B-3

The Engineering Behind The Midnight Aviator B-3 The Francis B-3 Leather Bomber Jacket is designed for men who require a functional layer that commands immediate attention. Most B-3 jackets use thin, synthetic materials; we engineered this piece with a high-density black shell that highlights the **Reinforced Vertical Seaming**, giving the torso a broader, more authoritative structure. 1. Dual-Strap “Storm Seal” Collar We utilized **Double-Industrial Throat Latches** on the collar. Originally designed for pilots in unheated cockpits, these straps allow you to lock the plush white collar upright, creating an airtight thermal shield for the neck and lower face. This integrated defense provides a significantly warmer winter solution than the lighter shells found in our Men’s Lightweight Jackets. 2. High-Contrast Thermal Architecture We installed **Exposed White Shearling-Style Trim** at the cuffs and hem. This construction ensures that heat-loss is minimized at every exit point of the garment while providing a sharp visual contrast against the onyx leather. This classic military style is a more robust, thermal-heavy alternative to the minimalist lines of our Men’s Cafe Racer Jackets. 3. Tactical Layering Mechanics This jacket features a **Broad-Shoulder Aviator Cut**. We engineered the torso to provide significant internal volume, allowing you to layer over heavy winter sweaters without restricting movement. For those who require a different material feel or a longer profile for executive environments, explore our Men’s Leather Coats for a classic long-form alternative. ⚠️ Critical Sizing Advisory This is a Handcrafted Garment. We cut this pattern for you. To ensure the perfect fit: The “Bulk” Factor: B-3 jackets are naturally thick. If you plan to wear multiple layers underneath, you MUST size up to maintain full range of motion. Collar Height: The dual straps are designed for a snug seal. Check the neck measurements in our Size Guide. Maintenance Tip: To maintain the onyx black depth and collar contrast, clean with a damp cloth and air dry. Do not iron the shearling-style trim.
