What Is PU Leather? How It Compares to Real and Vegan Leather

What is PU leather? It's a thin layer of polyurethane, a flexible plastic, spread over a fabric backing and pressed with a grain pattern so it looks like animal hide. It shows up on jackets, leggings, skirts, sneakers and bags, usually at a fraction of the price of the real thing.

The longer answer matters more, because PU sits inside a fog of marketing terms. Vegan leather, faux leather, pleather and leatherette all get used for overlapping things, and none of them tells you how long a piece will last before the surface starts to peel. Here's what the material actually is, how it compares to real leather, and how to read the label before you buy.

What Is PU Leather, Exactly?

PU stands for polyurethane, a family of plastics that can be rigid or soft and flexible. To make PU leather, manufacturers start with a base fabric, most often a polyester knit or woven, sometimes cotton, viscose or a nonwoven microfiber sheet. They coat or laminate it with one or more layers of polyurethane, then emboss the surface with a texture that mimics the pores and grain of cowhide or lambskin. A top finish adds color, sheen and some scratch resistance.

The result is two materials bonded together. The coating does the job of looking like leather and shedding water. The backing gives the material its strength, its stretch and most of its drape. That split explains a lot about how PU behaves, including why it fails the way it does.

A few hybrids are worth knowing. Bonded leather is made from leather scraps that are ground up, mixed with a binder, spread onto a backing and usually finished with a PU surface. Bicast leather is a lower layer of real hide, called a split, with a polyurethane layer on top. Both contain some real leather, but the surface you see and touch is plastic, and they tend to wear like PU rather than like hide. At the better end, microfiber leather uses a dense base of very fine synthetic fibers soaked through with PU, which feels closer to hide and usually lasts longer.

PU Leather vs Faux Leather vs Vegan Leather

These three terms aren't competitors. They nest inside each other.

Faux leather is the broad category: any material made to imitate leather. In clothing and accessories, it's almost always one of two plastics, PU or PVC (polyvinyl chloride, also called vinyl). Pleather and leatherette are casual names for the same category.

Vegan leather is a marketing term for any leather alternative made without animal products. That includes PU and PVC, which means most vegan leather on the market is plastic. It also includes newer plant based materials made from things like cactus, apple waste, pineapple leaf fiber or mushroom mycelium. Many of those still rely on a polyurethane binder or top coat to survive daily wear, so "plant based" on a tag rarely means plastic free.

PVC is the older, cheaper and stiffer option. It needs plasticizers to stay flexible, breathes even less than PU and tends to crack in the cold. PU is softer, thinner and drapes more like real leather, which is why it has largely replaced PVC in fashion. So the PU leather vs faux leather question has a simple answer: PU is a type of faux leather, and generally the better of the two common types for clothing.

Vegan Leather vs Real Leather

Real leather is tanned animal skin, a dense, three dimensional web of collagen fibers. That structure is why leather breathes, molds to your body over time and can be cleaned, conditioned and repaired. Scuffs can be buffed out, and a good leather jacket can outlive the person who bought it.

PU has none of that internal structure. Its look lives entirely in a surface layer, and once that layer is damaged there's nothing underneath but fabric. You can't condition PU back to health or sand out a deep scratch.

The case for PU is real, though. It costs much less, it's consistent from piece to piece with no scars or uneven dye, it's lighter, it resists water out of the box, and it involves no animal hide, which matters to a lot of shoppers. Some PU garments can even go in the washing machine.

The environmental picture is mixed. PU is a petroleum based plastic that doesn't biodegrade in any useful timeframe. Leather comes with livestock impacts and, in conventional chrome tanning, heavy chemical use. Neither is clean, so "vegan" is an animal welfare claim, not automatically a sustainability claim.

Is PU Leather Durable?

Moderately, and with a predictable failure mode. The classic complaint is peeling: the top layer flakes away from the backing in patches, starting where the material bends or rubs most. Collars, cuffs, elbows, the inner thighs of faux leather leggings and the spot where a bag strap sits on your shoulder go first.

The cause is partly mechanical and partly chemical. Every time the material flexes, the bond between coating and fabric takes a little stress. On top of that, polyurethane slowly breaks down through hydrolysis, a reaction with moisture in the air that heat and humidity speed up. That's why a PU jacket can start flaking after a few years even if it spent most of that time in a closet. Body oils, sunscreen and direct sunlight accelerate the process too.

How long you get depends heavily on quality. A thick, well bonded coating on a dense backing can look good for years of regular wear. A thin coating on a flimsy knit can crack within a season or two. Real leather, cared for, outlasts both by a wide margin, which is why it sits near the top of our list of the most durable fabrics for clothing.

The practical takeaway is to price PU as a piece with a limited lifespan. It makes sense for trend driven items, for pieces you'll wear occasionally and for anyone who doesn't want animal products. It makes less sense as a forever jacket.

Breathability and Comfort

This is PU's biggest weakness as a clothing material. Polyurethane coatings let very little air or water vapor through, so sweat has nowhere to go. A PU jacket worn indoors or a pair of faux leather leggings on a warm day can feel clammy fast, and the coating holds onto heat.

Real leather isn't a summer fabric either, but its fiber structure absorbs and releases moisture vapor in a way a plastic film can't.

Because the coating doesn't breathe, the lining and the backing do a lot of the comfort work. A PU jacket lined in cotton or viscose will feel noticeably better than one lined in polyester, which adds a second layer that doesn't absorb sweat. Our guide on whether 100% polyester is bad explains why that lining choice matters more than it looks.

How to Tell PU From Real Leather

Start with the label, because it's the most reliable test. Faux leather garments usually list the coating and the base separately, along the lines of "Coating: 100% polyurethane, Base: 100% polyester," or a shell of polyurethane with the backing listed underneath. Phrases like faux leather, vegan leather, man made materials or synthetic upper on shoes all point to PU or PVC. Real leather will say leather or name the hide, like lambskin or cowhide. Our guide to reading clothing labels covers the rest of the tag.

When you scan a faux leather label with WearScore, the app grades the fabric fibers it recognizes, which for PU is usually the polyester or cotton base and the lining. It doesn't grade the polyurethane coating itself. Read the grade as a verdict on the fabric underneath and inside, and judge the coating with the checks below.

If there's no label, look at the edges and the back. Real leather has a fibrous, suede like underside and cut edges that look dense and slightly fuzzy. PU shows a woven or knit fabric under the coating, and cut edges often reveal a distinct layer of plastic over cloth.

The surface gives clues too. Real leather grain is irregular, with pores that vary in size and spacing. PU grain is embossed, so the pattern often repeats or looks too even. Leather has a rich, earthy smell, while PU smells faintly of plastic, especially when new. None of these tests is perfect on its own, but together they're reliable.

How to Care for PU Leather

PU is low maintenance, but heat and harsh cleaners shorten its life. For everyday cleaning, wipe the surface with a soft cloth dampened with water and a drop of mild soap, then dry it with a clean cloth. Skip leather conditioners. They're formulated to soak into hide, and on a plastic surface they mostly leave residue, while solvent based cleaners can soften or damage the coating.

Some PU garments, especially faux leather leggings and lightweight skirts, are labeled machine washable. If yours is, turn it inside out, use cold water and a gentle cycle, and skip the dryer entirely. High heat can make the coating tacky, set permanent wrinkles or crack it as it cools. Never iron PU directly. Hang a wrinkled piece in a steamy bathroom instead.

Storage matters more than most people expect because of hydrolysis. Hang jackets on wide, padded hangers so the shoulders don't crease, keep them out of direct sunlight, and store them somewhere cool and dry rather than sealed in plastic, which traps humidity. Avoid folding PU sharply for long periods, since creases become crack lines.

Is PU Leather Worth It for What You're Paying?

For the right piece, yes. PU gives you the look of leather for a fraction of the price, with easy cleaning, a consistent finish and no animal hide. A faux leather skirt, a trend jacket or a pair of leggings you'll wear for a few seasons are all reasonable uses.

Where PU disappoints is when it's priced like a long term investment. A coating that peels after a few years shouldn't cost what a well made leather jacket costs, and plenty of brands now charge premium prices for vegan leather that is standard PU on a polyester backing. The label tells you which one you're holding. Read the coating and the base, check what the lining is made of, and scan it with WearScore to see how the fabric underneath grades. Then decide whether the price matches a piece with a built in expiry date.
