PU & synthetic leather
PU and synthetic leather deliver a leather appearance at lower cost, lighter weight and far more consistent colour than natural hide.
These materials are a polyurethane coating over a fabric backing, which means thickness, surface texture and finish are all specifiable. Litchi grain, saffiano, pebbled, matte and patent finishes are routine, and embossing or printing can be applied to the surface.
For brands the practical advantages are predictability and cutting yield. A roll of PU cuts with far less waste than a natural hide, which matters at short quantities where material waste has a visible effect on unit cost. PU also supports vegan product positioning without a price premium.
The trade-off is lifespan: surface coatings eventually crack or peel with heavy use, and grade quality varies widely between suppliers. Specify the grade and backing rather than simply asking for "PU".

Genuine leather
Genuine leather is offered for premium lines where hand-feel, patina and perceived value justify a higher cost and a longer lead time.
Full-grain retains the natural surface and ages best; top-grain is sanded for a more uniform appearance; split leather comes from the lower layer and behaves quite differently from either. Thickness, tanning and edge finishing are all specified alongside the hide selection.
Be honest with yourself about the trade-offs before committing. Leather is heavier, more expensive, slower to source in consistent colour, and shows natural grain variation that some retail customers read as a defect. Minimum quantities also tend to rise because hides are purchased in batches.
A common approach for a first market test is to prototype in leather, then launch the volume run in a high-grade PU while the design proves itself.

Polyester & nylon (Oxford fabrics)
Polyester and nylon Oxford fabrics are the workhorses of backpacks, travel bags and commuter styles, chosen by denier and coating.
Denier measures yarn thickness, which is why spec sheets list 210D, 420D, 600D, 900D and 1680D. Higher denier means a heavier, more abrasion-resistant fabric. 600D is the common mid-point for everyday backpacks; 900D and above suits heavy-duty and tool applications; 210D to 420D is typical for linings and lightweight packable bags.
Between the two fibres, nylon is lighter, softer in hand and more abrasion-resistant for a given weight, which is why technical and outdoor-leaning products lean nylon. Polyester holds colour better under UV exposure, resists water slightly better untreated and costs less, which is why most volume commuter and promotional products lean polyester.
Both are usually coated with PU, PVC or TPU for water resistance. The coating is specified separately from the fabric — two bags in "600D polyester" can perform very differently depending on what is on the back of it.

Canvas & cotton blends
Canvas offers a natural, printable surface that suits totes, lifestyle bags and branded promotional lines.
Canvas is a heavy plain-weave cotton or cotton-polyester blend, specified by weight — commonly 8oz to 16oz for bags. Heavier canvas gives more structure and a more substantial hand. Waxed finishes add water resistance and a distinctive appearance that ages visibly.
Print behaviour is canvas's biggest commercial advantage: screen printing is inexpensive and the natural surface reads as honest and unfussy, which is why branded totes default to it. Poly-canvas blends additionally accept sublimation printing.
Its limits are weight and water behaviour. Untreated cotton absorbs water and dries slowly, and a heavy canvas bag is noticeably heavier empty than a nylon equivalent of the same size.
