Coated leather is leather with a protective polymer film — usually polyurethane or acrylic — applied to the surface. The coating seals the hide, giving even colour, water resistance and easy cleaning. Uncoated leather is dyed through and left bare: it breathes, ages into a patina, and absorbs stains readily.
Knowing which you own matters, because the care routines are close to opposite.
The 10-second test
Place a drop of water on a hidden spot — under a strap, inside a flap.
- Soaks in and darkens within seconds → uncoated
- Beads briefly, then slowly darkens → semi-aniline
- Sits on top and wipes away clean → coated
Why it changes your routine
Coated leather needs gentle cleaning and very little conditioning. Conditioner can't penetrate a sealed surface, so heavy creams sit on top as a greasy film that attracts dust — and in humid air, feeds mould. Two or three light applications a year is plenty.
Uncoated leather needs the opposite: conditioning every two to three months to replace natural oils, and fast blotting of spills before they set.
The part most people get wrong
Coated leather isn't safe from mould — it's just slower to show it. Mould grows on the film of skin oil and dust sitting on top of the coating, and in the untreated linings, edges and stitching underneath. Because the coating slows moisture from escaping, a bag that gets damp inside can stay damp for weeks.
In Singapore's 84% year-round humidity, storage matters more than finish: breathable dust bags, air gaps between items, and something managing the air in the wardrobe itself.
