1. Why leather jacket maintenance changes everything
A well-maintained leather jacket lasts two to three times longer than an unmaintained jacket, assuming the same initial quality. This is what we observe on pieces that return to the showroom, and what every artisan who works with leather long-term confirms.
Full-grain leather is a living material. It breathes, absorbs and reacts to its environment. Left untreated it dries out gradually: the fibres lose their suppleness, the surface starts to crack where it creases (elbows, underarms, collar), and those cracks are irreversible. The process is slow and invisible, right up to the day it becomes very visible.
Exceptional leathers — those that retain the natural surface of the hide without sanding or correction — are both the most beautiful and the most valuable. This is precisely the type of material we select from the best European tanneries. The good news: maintenance only costs €25 to €35 in products per year.
Untreated leather can progressively deteriorate. Sometimes you only notice it when it's too late, with the first cracks appearing. A simple cleaning once a year or every two years is enough to prevent this.
2. The 4 enemies of full-grain leather
Four factors significantly degrade leather: dry heat, poorly managed humidity, unsuitable chemicals, and storage under compression. Understanding these risks can prevent 95% of damage.
Dry heat
Radiators, tumble dryers, hairdryers, prolonged direct sun: any source of dry heat speeds up the dehydration of the fibres. The cracks that follow appear first in the creases and are permanent. A wet jacket must be air-dried, away from any heat source.
Poorly managed humidity
Rain itself does not destroy leather. Bad drying does. A poorly dried jacket can develop water marks, stiff patches, or even mould if it is put away still damp. Always dry it flat or on a hanger, at room temperature, before putting it away.
Chemicals
Alcohol, white spirit, acetone, multi-surface household cleaners, silicone creams: all of these deeply attack the leather's grain. Silicone creates an artificial waterproofing that prevents the leather from breathing. "Leather" products found in supermarkets are often unsuitable for fine full-grain leathers.
Compression storage
Folded in a suitcase, crammed between other clothes, laid flat under a weight: leather remembers pressure. Crease marks that appear after prolonged storage are often impossible to remove. A leather jacket should always be stored hung on a wide hanger.
Never direct heat, never damp storage, never non-leather specific products, never folded for storage. These four rules prevent almost all irreversible damage.
3. First care: on arrival, before the first wear
The first maintenance is done upon receipt, before the first wear. This is the most important step in the entire life of the garment, and the one that almost all buyers forget.
A jacket usually arrives in a correctly hydrated state, but it has traveled and been stored in a warehouse. Its surface is ready to absorb — this is exactly the right time for a first preventive conditioning.
Check for any very dry areas. Identify areas that need treatment: elbows, shoulders, neck.
Lightly wipe the entire outer surface, without rubbing. Remove particles before applying cream.
A thin layer, focusing on the creases. Less is more.
On a hanger, at room temperature. No heat to speed up the process.
Remove excess cream. The leather should be slightly shinier, but not greasy.
Even layer over the entire surface. Let dry for 10 minutes.
Nourish and waterproof upon receipt, before the first wear. This is the most impactful step in the jacket's entire lifespan.
4. Routine maintenance: the right moves for each season
A leather jacket only needs to be conditioned once a year — but at the right time. Seasonal care follows a simple rhythm: conditioning and waterproofing in autumn, winter protection, careful storage in summer.
Autumn · September
- Waterproof, every year
- Condition, every year
- Clean according to use
- Check the zips and the seams
Winter · November to February
- Air dry after every rain
- Never place on a radiator
- Hang on a hanger every evening
- Reapply spray if exposed to intense conditions
Spring · March to May
- Treat stains if necessary
- Inspect folding areas
- Prepare for summer storage
Summer · June to August
- Storage on a padded wooden hanger
- Breathable fabric cover
- Cool, dry place, out of direct sunlight
- Never use plastic covers
Three habits after wearing it
Air it before putting it away. After wearing, leave the jacket on a hanger for a few minutes before it goes back in the wardrobe. Body heat will have slightly dampened the leather from the inside, and a short airing prevents condensation and lingering odours.
Wipe off surface moisture. If the jacket has caught light rain or perspiration, wipe the affected areas with a dry cloth before hanging it. Never put it away damp, even slightly.
Always hang, never fold. Leather keeps the shape it is given, permanently. A wooden hanger with shoulders wide enough to carry the cut of the jacket is the bare minimum.
5. Deep cleaning: once a year is enough
Once a year. The ideal time: early autumn, before the rain sets in. This annual cleaning covers everything—cleaning, conditioning, waterproofing—in a single 45-minute session.
We focus on areas that people usually don't look at: the inner collar, the cuffs, the seams around the fastenings. That's where it degrades first, and that's where we notice it too late.
Never wet dusty leather: it is the surest way to scratch the grain and drive the debris in. Use a soft-bristled brush over the whole jacket, seams included.
Test the cleaner on an inconspicuous area (e.g., inside a sleeve). Dilute it slightly and apply with a damp cloth in small circular motions. Pay special attention to the collar, cuffs, and elbows.
Air dry on a hanger for 30 to 60 minutes. The leather must be perfectly dry before the cream goes on: applied to damp leather, it will not penetrate.
Apply the nourishing cream sparingly, in circular motions, over the entire surface. Less is more. Let it penetrate for 15 to 20 minutes.
Buff with a dry cloth, then apply the waterproofing spray from a distance of 20 cm, using regular strokes, including on the seams. Allow to dry for 30 minutes before wearing.
6. Waterproofing the jacket without suffocating it
A full-grain leather jacket is naturally resistant to light moisture. Regular waterproofing restores this natural resistance without altering the leather's breathability or changing its appearance.
When should you waterproof? Once a year, after the annual autumn clean. On new leather, waterproof before the first wear.
Spray or cream? On smooth leathers (nappa lambskin, deerskin) spray is better: it penetrates more evenly. On suede, use only a dedicated suede spray, never a smooth-leather spray, which would stain the surface beyond repair.
The technique: hold the spray 20 cm from the surface. Work in regular horizontal passes, without dwelling on one spot. Cover the whole surface, seams and creased areas included. Leave to air dry for 20 to 30 minutes.
Some sprays darken natural-toned leather slightly: always test on a hidden area first.
7. Treating a stain: the protocol for each type
Almost all irreparable damage does not come from the stain itself. It comes from what was done in the minute that followed. The rule: blot, never rub, with the right product, at the right moment.
| Stain type | Recommended protocol | Absolutely avoid |
|---|---|---|
| Rain / water | Air dry naturally, on a hanger. Do not touch it while it dries. | Hairdryer, radiator, rubbing with a cloth |
| Fresh stain (coffee, wine) | Blot immediately with a dry microfibre cloth, without rubbing. Absorb without spreading. | Rubbing, reaching for wet products in a panic |
| Grease stain (oil, butter) | Cover with Sommières clay, leave to absorb overnight, brush off gently. | Water, detergent, alcohol |
| Dried water mark | Dampen the whole area lightly to even it out, leave to dry, then condition. | Treating the mark on its own |
| Ink stain | A delicate case. Hand it to a leather professional. Do not attempt it yourself. | Surgical spirit, nail polish remover, rubbing |
| Mould | Brush dry, clean with diluted white vinegar, leave to dry, then condition. | Plenty of water, the washing machine |
Blot, never rub. No alcohol, no white spirit, no household products. When in doubt, do nothing and ask, rather than making it worse.
8. What you can fix yourself — and what to leave to a professional
A quality jacket can be repaired or restored in the vast majority of cases, provided action is taken at the right time. The cost of a professional repair (€50 to €150) is always less than replacement.
On full-grain leather, light scratches often fade with a gentle rub and the application of a nourishing cream.
Dull leather responds very well to careful conditioning. Two applications 24 hours apart are often enough.
A lightly tinted cream (the Saphir range) evens out faded areas. Test on a hidden area.
When the leather is deeply cracked, only a specialist leather workshop can step in, with the right restoration products.
A faulty RiRi or YKK Excella zip can be replaced by a cobbler or a leather workshop. Ask for the same type of zip.
The lining can be re-stitched or replaced by a specialist workshop, not by a general cobbler.
Engine oil, ink, red wine: a professional has solvents and dyes compatible with the tanning of your leather.
9. Storage: the rules that avoid the worst
Summer storage is responsible for some of the damage we see reappearing in September. Three months in a plastic cover, folded in a hot closet, and a jacket worn without issue for five years ends up with stains.
Proper storage
- Wide wooden hanger with shaped shoulders
- Cotton or breathable fabric garment bag
- Cool, dry, well-ventilated place
- Away from direct light
- After cleaning and conditioning
To avoid at all costs
- Airtight plastic cover
- Folded or compressed in a drawer
- Thin metal hanger
- Drying near a radiator
- Storage without prior cleaning
10. Products: what we recommend, what we avoid
Three products. That's all it takes for the annual maintenance of a full-grain leather jacket. Generic supermarket products almost systematically contain silicone: in the short term it shines, in the long term it chokes the leather.
The three essentials: a colourless conditioning cream based on beeswax or lanolin and free of silicone (Saphir Rénovateur is the easiest to find); a waterproofing spray for smooth leather based on natural wax (Saphir Super Invulner); and a soft microfibre cloth for applying and buffing.
To use
- Saphir Rénovateur — colourless, silicone-free conditioning cream
- Saphir Super Invulner — natural-wax waterproofing spray
- Soft microfibre cloth — applying and buffing
- Sommières clay — grease stains only
Never use
- Silicone products — suffocate the leather permanently
- Alcohol, white spirit, acetone — destroy the grain
- Petroleum jelly or vegetable oil — turn rancid in the fibres
- Multi-surface household cleaners — too harsh
- Marseille soap — alkaline, weakens the fibres
A simple rule: if a product does not explicitly state "for untreated leather" or "silicone-free", do not use it. The leathers selected at Atelier Bertrand are untreated hides, whose natural surface reacts strongly to unsuitable products.
11. Care by leather type: nappa lambskin, deerskin, suede
The three materials used at Atelier Bertrand — lambskin, deerskin and suede — have different needs. Nappa lambskin and deerskin are smooth leathers and follow the same protocol. Suede is a reversed leather and follows completely different rules.
Bodin Joyeux EPV nappa lambskin
Lambskin is the most delicate of the three. Its very fine grain and extreme suppleness also make it the most vulnerable to abrasion and to drying out. One conditioning a year is enough, at the start of autumn. The quality of the tanning gives it good natural resistance, and too much cream softens the fibres and can distort the garment.
Deerskin
Deerskin is an exceptional leather: supple, warm to the hand, with a slightly irregular natural grain. More abrasion-resistant than lambskin, it takes a particularly fine patina. The protocol is the same: condition once a year in autumn, and waterproof without fail. Deerskin is more sensitive to grease stains, and Sommières clay is the best ally there.
Suede (lambskin and calfskin)
Suede is a reversed leather: the inner side of the hide is the face that shows. Its care is fundamentally different from smooth leather, and it does not forgive mistakes.
Never on suede: no ordinary conditioning cream, no standard waterproofing spray, no direct water. These stain the surface, mat the nap together, or leave irreversible rings.
What to use: a suede brush to lift the nap back in one direction; a suede eraser for light marks; and, for waterproofing, only a dedicated suede spray. Always test on a hidden area.
12. Working out the annual cost: the decisive argument
An Atelier Bertrand jacket at €990, properly maintained over twenty years, costs €60 per year all inclusive. Less than a faux leather jacket replaced every three years — and quality leather, for its part, gains character with time.
| Type of jacket | Purchase price | Lifespan | Cost / year | Care / year | Total / year |
|---|---|---|---|---|---|
| Mass-market faux leather | €120–€200 | 2–3 years | €55–€80 | — | €55–€80 |
| Mid-range corrected-grain leather | €300–€500 | 5–8 years | €45–€75 | €20 | €65–€95 |
| Atelier Bertrand — EPV leather | €990–€2,220 | 20–30 years | €40–€90 | €20–€25 | €60–€115 |
| Luxury house | €3,500–€6,000 | 20–30 years | €140–€250 | €20–€25 | €160–€275 |
Maintenance is not just another cost. It's what separates a purchase from an investment.
