FREQUENTLY ASKED QUESTIONS
What is Real Merino shearling and why is it used in aviator jackets?
Real Merino shearling is sheepskin with the wool still attached—the hide and fleece together. Merino sheep produce finer, softer wool than standard breeds, making Merino shearling exceptionally warm without excessive weight. Originally chosen for 1940s B-3 flight jackets worn by open-cockpit pilots, shearling provides superior insulation at altitude where temperatures plummet. The fleece traps warm air while remaining breathable, so you stay comfortable during layering. Unlike synthetic alternatives, genuine shearling develops a natural patina over time, making each jacket unique. It's durable, water-resistant, and ages beautifully with proper care.
How do I order a made-to-measure aviator shearling jacket?
Ordering a made-to-measure aviator shearling jacket is straightforward. First, select Custom Size from the product options Size dropdown on the product page, then complete checkout as normal. After your order is confirmed, you'll receive an order number. Visit the measurement form and enter your order number along with your body measurements (chest, waist, sleeve length, and any other custom fit notes). Once we receive your measurements, our team confirms the specs and your jacket enters production. Custom orders ship in 4–6 weeks from spec confirmation. Standard sizes (XS to XXL) ship in 10–15 working days, so choose based on whether you want a tailored fit or faster turnaround.
Can I customize the lining on the B-3 shearling bomber?
Yes. The B-3 shearling bomber offers a choice of lining at checkout: Real Merino Shearling (default) or Artificial Fur. Both options provide excellent warmth and comfort. Real Merino shearling delivers the authentic heritage experience with natural breathability and durability—it's the original choice for vintage aviator jackets. Artificial fur offers a lighter, easier-care alternative while maintaining the classic B-3 aesthetic. Choose based on your climate, care preferences, and budget. If you're ordering custom sizing, you can select your preferred lining during the measurement form submission as well.
What's the lead time for standard versus made-to-measure orders?
Standard sizes (XS to XXL) ship in 10–15 working days from order confirmation. This is our regular production window for off-the-shelf sizing. Made-to-measure custom orders take longer because each jacket is hand-stitched to your exact measurements. Once you submit your body measurements via the measurement form, our team reviews and confirms the specs (typically within 2–3 business days). Production then begins, and your custom jacket ships in 4–6 weeks from spec confirmation. Total timeline for custom sizing is usually 4–6.5 weeks. All orders ship worldwide with tracking. See our shipping & delivery page for detailed information.
How do I care for and maintain Real Merino shearling leather?
Real Merino shearling is durable and low-maintenance when cared for properly. Brush the fleece gently with a soft-bristled brush every few weeks to restore texture and remove dust. For light surface stains on the leather, wipe with a damp cloth and let air-dry away from direct heat or sunlight. Avoid machine washing, dry cleaning, or harsh chemicals. Condition the leather trim (lambskin) once or twice a year using a leather conditioner designed for shearling—this keeps it supple and extends lifespan. Store in a cool, dry place on a padded hanger; avoid plastic bags (they trap moisture). Over time, the brown leather will develop a natural patina—this is normal and adds character. For stubborn stains or professional cleaning, consult a leather specialist familiar with shearling garments.
