Built around the practical look of classic RAF flight jackets, this black sheepskin leather jacket combines a slim-fit silhouette with substantial winter construction. It is made from approximately 1.4mm sheepskin leather and weighs around 2.0kg, giving it a structured feel and dependable warmth without looking oversized.
The smooth black leather, shearling-lined collar and strap-front closure create a strong military-inspired appearance that works with denim, cargo trousers, knitwear and winter boots. For more naturally insulated styles, explore our shearling leather jacket collection.
At approximately 1.4mm, the leather is thicker and more substantial than lightweight fashion sheepskin commonly used in 0.7mm–0.9mm jackets. This added body helps the jacket retain its shape, resist everyday abrasion and provide better protection against cold air.
The 2.0kg weight reflects the jacket’s heavier winter build, shearling details and structured panels. It is suitable for people who want a warm, substantial jacket rather than an ultralight layer. The slim fit keeps the profile neat, but leave enough room for a thermal shirt or medium-weight sweater underneath.
The front uses an original YKK #8 metallic zipper as the main closure. Over the zipper are three horizontal leather straps secured with metal buckles. This is a RAF-style strap-and-buckle fastening system rather than a simple decorative belt.
The straps add visual character while helping hold the front securely against the body. When fastened over the zipper, they also reduce openings where cold air can enter. Each strap is attached with reinforced rectangular stitching, giving the fastening points additional support during repeated use.
A shearling-lined collar provides soft insulation around the neck and strengthens the jacket’s traditional flight-jacket appearance. The collar can be worn open for a more relaxed look or secured closer to the neck when temperatures fall.
Matching shearling trim at the cuffs adds warmth around the wrists and creates a clear contrast against the black leather sleeves. Together, the collar and cuffs make the jacket especially useful for cold commutes, outdoor travel and winter evenings.
Clean and tonal topstitching that follows the jacket’s main construction lines. Single-row edge stitching is visible around the front zipper placket, shoulder seams, sleeve joins and pocket openings, keeping the finish sharp without distracting from the black leather.
The three strap tabs use rectangular reinforcement stitching at their anchor points. A central vertical seam gives the front a structured appearance, while the back panel and shoulder seams are finished with evenly spaced tonal stitching to support the slim-fit shape.
This combination of edge stitching and reinforced strap attachment is appropriate for a jacket that receives regular movement around the chest, shoulders and arms.
The exterior hand pockets provide convenient storage and a comfortable place to warm your hands. Their clean placement keeps the front profile streamlined despite the additional strap hardware.
One interior pocket offers more discreet storage for a phone, wallet, keys or travel documents. Keep heavier items in the inside pocket rather than overloading the outer pockets, as this helps the slim silhouette hang correctly.
This jacket suits men who want:
A warm winter jacket with a slim, structured fit
RAF, military or aviation-inspired styling
Genuine sheepskin instead of synthetic outerwear
A more substantial alternative to a lightweight leather bomber
Practical front and interior storage
A distinctive strap-and-buckle closure over a reliable YKK zipper
It is designed for fashion, warmth and everyday winter use. It should not be treated as certified motorcycle protection unless armour and riding certification are specifically stated.
The 1.4mm sheepskin shell, shearling details and multi-point front closure make this jacket suitable for cold and moderately windy conditions. It works well for winter commuting, travel, outdoor walks and casual evening wear.
Leather and shearling are not waterproof materials. Avoid prolonged rain, heavy snow and soaking. If the jacket becomes wet, allow it to dry naturally at room temperature and keep it away from radiators, heaters and tumble dryers.
Remove surface dust with a soft brush or dry cloth.
Brush the shearling gently in the direction of the wool.
Never machine wash, iron or tumble dry the jacket.
Do not use household detergent, alcohol-based sprays or standard shoe polish.
Apply conditioner only to the leather side, and test it on a hidden area first.
Avoid frequent conditioning because over-conditioning can soften or darken the leather unevenly.
Keep the YKK zipper free from dust and wool fibres; never force it if the teeth are misaligned.
Use only a leather-safe zipper lubricant when necessary.
Wipe the metal buckles dry after exposure to moisture.
For stains or deep cleaning, use a professional cleaner experienced with sheepskin and shearling garments.
Store the jacket on a broad hanger in a cool, ventilated place.
