Care for
Leather
Right
Cowhide Leather Jacket
The Wulbi cowhide jacket is cut from full-grain leather — the outermost, most durable layer of the hide, with its natural grain intact. Unlike corrected or bonded leather, full-grain leather does not have a uniform surface. It marks, softens, and develops character with every wear. That is not a flaw — it is the material behaving as it should.
Leather Conditioner
A cream or balm conditioner (not spray). Brands like Leather Honey, Saphir Renovateur, or Chamberlain's are excellent. Apply every 3–6 months or after any heavy rain.
Soft Cloth
A clean, lint-free microfibre or cotton cloth for wiping down the surface before conditioning. Never use paper towels — they leave micro-scratches on leather over time.
Leather Protector Spray
A water and stain repellent spray applied before first wear and refreshed seasonally. Creates an invisible barrier without affecting the natural finish or breathability.
Padded Hanger
A wide, padded or wooden hanger that supports the full shoulder width. Narrow wire hangers will distort the shoulder shape of a leather jacket over time.
Use a clean, dry cloth to remove any surface dust, dirt, or light marks. For stubborn spots, a cloth barely dampened with water — wrung out thoroughly — is sufficient. Never saturate the leather.
Apply a small amount of leather conditioner to a clean cloth and work into the surface in slow, circular motions. Pay particular attention to the elbows, collar, and cuffs — areas that flex the most and dry out fastest.
Let the conditioner absorb for at least 30 minutes — ideally overnight. The leather will darken temporarily as it drinks in the conditioner, then lighten again as it sets. This is normal.
Buff lightly with a clean cloth to remove any excess. Hang on a padded hanger in a cool, dry space with good airflow. A breathable cotton garment bag is ideal. Never use plastic — leather must breathe in storage.
Repeat this routine at the start and end of each wearing season, or after any prolonged rain exposure.
Do
- Hang on a wide padded hanger whenever not in use
- Condition every 3–6 months, or after any heavy rain
- Apply protector spray before first wear and each new season
- Air the jacket after wear before storing — especially after perspiration
- Allow wet leather to dry fully at room temperature before conditioning
- Spot clean small marks immediately with a clean damp cloth
Avoid
- Drying with a hairdryer, radiator, or any direct heat source
- Machine washing or dry cleaning — both destroy full-grain leather
- Folding or storing compressed — causes permanent crease lines
- Storing in plastic — traps moisture and causes mildew
- Silicone-based leather products — they block the pores of the hide
- Leaving damp leather unattended — always dry before storing
Do not panic — and do not apply heat.
Full-grain leather can tolerate rain without permanent damage if handled correctly afterwards. It is not the water that damages leather — it is the cycle of drying without conditioning that causes cracking and stiffness.
- Blot excess water immediately with a clean dry cloth. Do not rub.
- Hang on a padded hanger and allow to dry naturally at room temperature — this may take several hours.
- Once fully dry, apply a generous coat of leather conditioner to restore suppleness across the entire jacket.
- Buff lightly once absorbed. The jacket will look and feel as good as before.
The Leather
Develops
Patina is not damage. It is the leather's record of being worn.
Full-grain cowhide develops a patina over time — a gradual deepening of tone, a softening of the surface, subtle variations in colour that accumulate at areas of flex and contact. No two jackets age identically. Your jacket will look different from anyone else's, shaped by the specific way you move, carry, and wear it.
A light surface scuff on full-grain leather can often be buffed out with a clean finger — the natural oils in your skin are enough to work it back in. Deeper scuffs can be treated with a matching leather cream, applied sparingly and worked in slowly. Over time, even these will blend into the overall surface character of the jacket.
Resist the urge to return the jacket to its original appearance. The most beautiful leather pieces are the ones that have been genuinely used.
The single most important habit for leather jacket longevity is simple: hang it up after every wear. Leaving a leather jacket folded, creased, or bundled — even overnight — is how permanent distortion begins. Two minutes on a hanger adds years to the life of the piece.
Cowhide Trucker Cap
The Wulbi cowhide trucker cap pairs a full-grain leather front panel with a mesh back and snapback closure. The leather panel is stiffer than the jacket — it is designed to hold a structured shape — but it responds to the same care principles. Treat the leather panel; leave the mesh to air naturally.
Leather Conditioner
A light cream conditioner applied sparingly to the front panel only. A small amount goes a long way on a structured panel — do not saturate or the shape may soften.
Soft Brush or Cloth
A soft bristle brush (like a shoe brush) or clean cotton cloth for removing surface dust from the leather panel before conditioning.
Leather Protector Spray
Apply before first wear and after each season. Hold the can 20–25 cm from the cap and apply an even, light coat to the leather panel only. Avoid spraying the mesh.
Cap Form or Shelf
Store on a cap form, hat hook, or flat on a shelf — never stacked under other items. The structured brim is designed to hold its shape but will distort under weight.
Use a soft dry brush or cloth to remove any surface dust or debris from the leather front panel. Brush gently in one direction — never scrub against the grain of the leather.
Apply a very small amount of conditioner — about the size of a pea — to a cloth and work it evenly across the leather panel. A little goes a long way. Over-conditioning a structured panel will soften its shape.
Allow the conditioner to absorb for 20–30 minutes. The panel may temporarily appear slightly darker, then return to its normal tone as the leather drinks in the moisture.
Buff gently with a clean cloth. Leave the cap somewhere with airflow for an hour before wearing or storing. Store on a hook or cap form — never squashed into a bag.
Condition the leather panel every 2–3 months during regular use, or whenever the surface begins to look or feel dry.
Cleaning the interior without wetting the leather.
The interior sweatband will absorb perspiration with regular wear. Clean it carefully — the goal is to clean the band without soaking the structured leather panel above it.
- Use a cloth barely dampened with cool water and a small drop of mild soap.
- Gently wipe the sweatband only — avoid letting water run onto the leather front panel.
- Air dry fully before wearing again. Do not use a dryer or direct heat.
- If the leather panel accidentally gets wet, blot immediately and allow to dry at room temperature before conditioning.
Do
- Store on a hook or cap form to maintain the brim shape
- Apply protector spray before first wear
- Condition the leather panel lightly every 2–3 months
- Air after sweaty wear before storing
- Clean the sweatband separately with a barely damp cloth
Avoid
- Machine washing — the leather panel cannot withstand submersion
- Stacking other items on top during storage
- Over-conditioning — softens the structured panel shape
- Wearing in heavy rain without a protector coating
- Drying with any heat source — always air dry naturally
The cowhide front panel is designed to stiffen slightly more than jacket leather — this is intentional, so the cap holds its structured silhouette. Do not attempt to soften the panel significantly with heavy conditioning. A light, regular application is far better than occasional heavy treatments. Think of it as hydration, not restoration.
Leather Sneakers
The Wulbi Apex Low-Top (full-grain cowhide) and HTN Pony Hair Low-Top (pony hair panels, cowhide base) require different care approaches. The Apex responds to standard leather conditioning. The HTN pony hair panels are more delicate — they are brushed in one direction and must be kept away from moisture entirely.
Leather Conditioner
A light cream conditioner applied to the leather upper. Saphir Médaille d'Or Crème Universelle or Leather Honey are both excellent. Apply monthly during regular wear.
Soft Shoe Brush
A natural bristle brush for removing surface dust and debris before conditioning. For the HTN, use a separate, very soft brush reserved for the pony hair panels only — always in one direction.
Shoe Trees
Cedar shoe trees inserted after each wear. They absorb moisture from inside the shoe, prevent the upper from creasing, and maintain the last shape through years of wear. Non-negotiable for leather footwear.
Leather Protector Spray
Apply to the Apex upper before first wear and refresh monthly. For the HTN pony hair panels, do not use spray — the panels need a dry specialist protector applied by a cobbler if needed.
Remove the shoes and immediately brush off any surface dirt with a soft brush before it sets. Mud and grit are abrasive — the longer they sit, the more they work into the surface of the leather.
Insert cedar shoe trees immediately to absorb interior moisture from perspiration and maintain the shape of the upper. Leave them in until the next wear. This single habit prevents creasing more than any other.
Leave the shoes in open air — not inside a bag or box — for at least a few hours after wear. This allows remaining moisture to dissipate before storage. Never place near a radiator or in direct sunlight.
For the Apex, apply a small amount of leather conditioner to the upper once a month. For the HTN, inspect the pony hair panels for any debris or matting and brush gently in the direction of the grain only.
Monthly conditioning applies during active wear. In storage, condition before putting away and again before first wear of the new season.
Pony hair requires a different approach from standard leather.
The pony hair panels on the HTN are genuine hair-on hide. They have a directional grain that must be respected at all times. Moisture is the primary threat — even a light splash can permanently distort the hair pattern if rubbed while wet.
- Never rub pony hair — always brush in one consistent direction, following the natural grain.
- If the panels get wet, blot only with a dry cloth. Allow to dry completely, then brush back into alignment once fully dry.
- Never apply standard leather conditioner to pony hair panels — it mats the hair and leaves residue.
- The HTN is not designed for wet conditions. Avoid wearing in rain whenever possible.
The
Break-In
Period
Leather sneakers require time. Plan for 5–10 wears.
Full-grain leather footwear is firm on first wear by design. The material has not yet been shaped to your foot. Both the Apex and the HTN base will feel precise — potentially tight — for the first several wears. This is normal and expected.
The break-in process accelerates with short, frequent sessions rather than long first wears. Wear for 1–2 hours on your first few outings, rather than a full day. This allows the leather to begin conforming gradually, without blistering. Applying a leather conditioner to the upper before first wear softens the material slightly and makes the break-in process more comfortable.
After 5–10 wears, the leather will have begun to mould to the specific shape and width of your foot. At this point, the fit will feel noticeably more comfortable — and increasingly better with continued wear.
| Task | Apex Low-Top | HTN Pony Hair | Notes |
|---|---|---|---|
| Brush after wear | Every wear | Every wear | Before dirt sets into the surface |
| Cedar shoe trees | After every wear | After every wear | Non-negotiable for shape retention |
| Condition leather | Monthly | Base only, monthly | Never condition pony hair panels |
| Protector spray | Monthly | Base only | Avoid pony hair panels entirely |
| Deep clean | Seasonally | Cobbler only | Do not attempt to deep-clean HTN at home |
Frequency assumes regular wear (2–3 times per week). Adjust accordingly for occasional or heavy use.
Do
- Use cedar shoe trees after every single wear
- Condition the Apex upper monthly during active use
- Brush pony hair panels in one consistent direction only
- Apply protector spray to the Apex before first wear
- Allow both styles to fully air dry before storing
- Store in the original dust bags when not in use
Avoid
- Wearing the HTN in wet or rainy conditions
- Rubbing pony hair panels — always brush, never rub
- Applying conditioner to pony hair panels
- Storing without shoe trees — causes upper collapse and creasing
- Drying near any heat source after rain exposure
- Machine washing the insoles — remove and air them instead
A crease across the toe box of a leather sneaker is not a manufacturing defect — it is leather behaving as it should under flexion. Cedar shoe trees minimise this significantly when used consistently. For deep creases that have already formed, a leather conditioner applied and worked gently into the crease with your fingertip — followed by shoe trees overnight — will soften and reduce their appearance without eliminating them entirely. Embrace them: they are the leather recording your movement.
Universal Leather Rules
Regardless of the piece — jacket, cap, or sneaker — full-grain leather follows the same fundamental principles. Understand these and every leather piece you own will reward you for decades.
Heat is the primary cause of leather cracking, stiffening, and premature ageing. A radiator, hairdryer, or patch of direct sunlight will dry out the natural oils in the hide far faster than the leather can recover. Always air dry at room temperature, regardless of how long it takes.
The instinct is to condition a piece when you take it out after months in storage and it looks dry. The better habit is to condition before storing — this way the leather goes into its dormant period hydrated, and emerges in much better condition.
Full-grain leather tolerates rain, light splashes, and humidity reasonably well. What causes lasting damage is leaving wet leather to dry without conditioning. The sequence — blot, air dry, condition — prevents virtually all rain-related damage.
A light application of conditioner every 2–3 months does far more for leather than a saturating treatment once a year. Leather absorbs what it needs — excess conditioner sits on the surface, attracts dust, and can soften structured pieces beyond their intended shape.
Leather holds the shape it is stored in. A jacket left in a heap develops permanent fold lines. Sneakers stored without trees collapse at the toe box. A cap stacked under other items loses its brim curve. The way you store leather is as important as how you clean it.
