Restoring a Vintage 1970s Schott Leather Flight Jacket

Summer is officially over, and with colder weather rolling in, it was time to pull out my winter gear. Waiting in storage was a vintage Schott IS-674 flight jacket from around 1978 or 1979.

At nearly 50 years old, the leather had become stiff, dry, and worn down from decades of use. It needed serious care before hitting the streets again.

Here’s the step-by-step process I used to bring this classic piece of history back to life.

Watch the step-by-step restoration of this late-1970s Schott flight jacket, from saddle soap cleaning to deep conditioning and cuff repairs.

What You’ll Need

Saddle soap: Cleans off surface grime and preps the leather without soaking it.
Nourishing leather cream (like Saphir): The most critical step to restore essential oils and suppleness.
Leather wax (optional): Adds water resistance, protection, and a subtle shine.
Lint shaver / fabric defuzzer: Cleans up pilled ribbed cuffs and waistband elastic.
Awl or needle: Cleans oxidation off vintage snaps and hardware.
Clean microfiber cloths: For lathering, wiping, and buffing.
Heavy-duty waxed thread: For minor seam repairs.

Step 1: Surface Clean with Saddle Soap

Before adding oils back in, you have to get rid of decades of dirt.

Dampen a cloth or sponge slightly and work up a light lather with the saddle soap.
Focus especially on areas that sit against bare skin (like the collar), where body oils and dirt build up over time.
Don’t soak the leather—keep the moisture minimal.
Wipe away excess lather with a damp, clean cloth and let the surface dry.

Step 2: Clean the Hardware

Old brass and metal snaps often collect green verdigris (oxidation) around the edges.

Using the tip of a fine needle or awl, carefully scrape away the crust around the snaps without scratching the surrounding leather. It’s a small detail, but it instantly cleans up the vintage look.

Step 3: De-Pill the Ribbed Knit Cuffs and Waistband

Vintage flight jackets feature heavy knit elastic on the waistband and cuffs that tend to get fuzzy and pilled.

Run an electric fabric defuzzer over the knit trim to shave off pills and loose fuzz. It sharpens the silhouette immediately and makes worn ribbing look brand new.

Step 4: Deep Conditioning (The Crucial Step)

When leather dries out, internal fibers turn brittle and break instead of bending. Restoring the oils is what actually saves the jacket.

Work generous amounts of leather cream deep into the grain.
Pay extra attention to seams, folds, and high-movement areas like elbows and shoulders.
Note: Leather balm will darken lighter leathers at first, but the color balances out as the oils absorb fully.
Let the jacket sit so the fibers can soak in the nourishment. Once dry, buff away any surface haze with a soft cloth.

Step 5: Stitch Repairs & Finishing Wax

Mend the knit: If any seams on the ribbing have pulled loose, stitch them up using a sturdy waxed polyester thread.
Protective wax coat: Apply a very thin layer of leather wax to seal the finish. A little bit goes a long way. Once it dries to a haze, buff it vigorously with a clean rag for a rich, satin sheen.

The Final Result

The transformation is night and day. The leather went from cardboard-stiff to soft, supple, and comfortable to wear, while keeping every bit of its 50-year-old character and patina.
