Short Answer (Citable)

This answer applies to every jacket category a factory typically produces: fashion bombers, varsity jackets, workwear, commuter styles, and insulated or down jackets. In every case the shell fabric is the largest single cost and performance driver of the garment, which is why professional buyers treat fabric selection as the first major decision of a project, not an afterthought.

The Main Fabric Families for Custom Jackets

Nearly every custom jacket shell falls into one of four fabric families: nylon, polyester, cotton, or a blend of these. Each family has a distinct profile, and most collections mix families across styles so that a single brand can offer a technical line, a casual line, and a workwear line without changing factories.

• Nylon: lightweight, strong for its weight, abrasion-resistant, and quick-drying. It packs down small, which makes it the standard shell for insulated and packable jackets. Options range from fine 20D ripstop to heavy 300D oxford and cordura-style weaves for workwear.
• Polyester: colorfast, wrinkle-resistant, low cost, and easy to care for. It holds bright colors well and is widely used for fashion bombers, varsity bodies, linings, and fleece or sherpa interiors. It is usually the most economical option for a first collection.
• Cotton: natural hand feel, breathable, and classic in appearance. Canvas, twill, and poplin cotton suits chore coats, trucker jackets, and utility styles. Cotton is comfortable but heavier and slower to dry than synthetics, and it is often blended with nylon or polyester to improve durability.
• Blends: cotton-nylon and cotton-polyester blends combine the hand of natural fiber with the strength of synthetics. Polyester-spandex and nylon-spandex blends add stretch for active and commuter styles.
• Coated and treated fabrics: any of the families above can receive a DWR finish, a PU coating, or a laminated membrane to add water repellency, which extends the range of uses for the same base fabric.

Established manufacturers keep a library of proven fabrics in these families and can also source specialty materials per project. When you brief a factory, you are not limited to what is shown on a website; the practical constraint is usually minimum fabric order lengths and lead time, not the number of options.

Nylon vs. Polyester vs. Cotton: Fabric Comparison Table

Use this table as a starting point, not a final verdict. Two nylon fabrics can behave completely differently when the denier, weave, and finish change, so the family name alone is never enough to specify a jacket shell. The following sections explain the numbers that actually separate one fabric from another.

Denier, Fabric Weight, and Weave: Reading a Fabric Specification

When a manufacturer quotes a fabric, it usually comes with three pieces of information: denier, weight in grams per square meter, and weave construction. Understanding these three values lets you compare quotes from different factories and prevents the classic mistake of accepting a cheaper fabric that looks identical in a photo but performs differently in use.

• Denier (D): the thickness of the individual yarn filaments. Lower numbers mean finer, lighter fabric, while higher numbers mean heavier and tougher material. A 20D nylon is a featherweight shell, while a 600D polyester is a heavy, hard-wearing workwear fabric.
• GSM (grams per square meter): the weight of the finished fabric. Light shells and linings run around 60 to 100 GSM, mid-weight shells around 150 to 250 GSM, and heavy canvas or workwear fabrics above 300 GSM.
• Weave construction: plain, twill, ripstop, oxford, and canvas weaves change the hand, durability, and look of the same yarn. Ripstop adds a reinforced grid that stops tears from spreading, which is why it dominates outdoor shells.
• Finish: DWR coating, PU backing, brushing, and calendaring alter water resistance and softness without changing the base construction.

Put these four items in your tech pack in writing. A specification that reads "nylon shell, 40D, 80 GSM, ripstop, C0 DWR" tells the factory exactly what to source and prevents interpretation gaps during quotation and sampling.

Water-Repellent and Coated Fabrics for Jackets

Many jacket projects need some level of water resistance, and the market distinguishes three ways to achieve it. The differences matter because they change both the price and the breathability of the finished garment.

• DWR (durable water repellent): a chemical finish applied to the face of the fabric that makes water bead and roll off. It handles light rain and is standard on most outdoor and commuter shells. DWR wears off over time and can be refreshed with a spray-on or wash-in treatment.
• PU coating: a polymer layer applied to the back of the fabric that blocks water entirely for moderate rain. PU-coated nylon and polyester are common on rain jackets and entry-level weather shells, and they are inexpensive, but they are less breathable than membranes.
• TPU or PU lamination: a membrane bonded to the fabric in two-layer, two-and-a-half-layer, or three-layer constructions. Laminates offer the best balance of waterproofing and breathability and are the standard for serious outdoor and technical styles.
• Softshell: stretchy, bonded laminates that combine a knit or woven face with a membrane. Softshell is comfortable, quiet, and flexible, which makes it popular for commuter and transitional jackets.

Coated and laminated fabrics trade breathability for protection, so the right choice depends on how the jacket will be worn. A brand selling to a mild, rainy market may prefer a breathable DWR shell, while a brand targeting winter commuters may need a fully coated or laminated fabric.

Linings, Interlinings, and Pocketing Fabrics

When buyers ask about fabric options, they usually mean the outer shell, but a jacket contains several other fabrics that determine comfort, warmth, and construction quality. Discussing all of them at the quotation stage avoids surprises in the finished garment.

• Linings: polyester taffeta, nylon taffeta, brushed tricot, fleece, and quilted linings. A slippery lining makes a jacket easy to put on over knitwear, while a fleece lining adds warmth and a premium feel.
• Interlinings: fusible non-woven materials and weft inserts that give structure to collars, plackets, cuffs, and facings. They are invisible in the finished product but determine whether a collar stands up or flops.
• Pocketing: cotton twill or polyester pocketing for durability, plus fleece-lined hand warmer pockets and zippered security pockets for technical styles.
• Sleeve linings: slippery nylon or polyester that lets sleeves slide over shirts and sweaters, common in blazers and lined outerwear.

Ask the factory to quote the lining family together with the shell, because the two drive the garment together: a technical nylon shell with a cheap polyester taffeta lining can still feel hot and clammy in use, while the same shell with a breathable or brushed lining feels like a completely different product.

How to Choose a Jacket Fabric for Your Target Market

There is no single best jacket fabric, only the right fabric for a specific product and market. Professional buyers start from the end user: what the jacket is for, where it will be worn, and what the customer expects to pay. From there the fabric family, weight, and finish almost choose themselves.

• Fashion and lifestyle: cotton, cotton blends, and polyester with a focus on drape, color, and hand feel rather than technical performance. Bombers and varsity jackets typically sit in this group.
• Workwear and utility: heavy cotton canvas, cotton-nylon twill, and abrasion-resistant nylon, where durability, easy care, and pocket structure matter most.
• Outdoor and insulated: nylon and polyester shells, often coated or laminated, selected for lightweight packability and weather resistance. This is the standard group for down and puffer styles.
• Commuter and transitional: softshell, light PU-coated nylon, and stretch blends that balance protection, breathability, and freedom of movement.

Seasonality, care expectations, and retail price all influence the decision. A machine-washable polyester shell suits an entry-level fashion line, while a dry-clean-only wool-cotton blend suits a premium tailoring position. State the care label you want in your brief, because it limits which fabrics are viable.

Sustainable and Recycled Fabric Options

Sustainability is now a routine part of fabric sourcing for Western brands, and factories respond with a growing list of verified options. These materials usually carry a small price premium, but they also open doors with retailers that require environmental documentation.

• Recycled polyester (rPET) and recycled nylon: made from post-consumer bottles or reclaimed fishing nets, used for shells and linings in outdoor and fashion collections.
• Organic cotton and BCI cotton: grown with fewer chemicals, used for canvas, twill, and poplin styles where natural fiber is part of the brand story.
• OEKO-TEX Standard 100 certified fabrics: tested for restricted substances, which reassures retail buyers and simplifies compliance documentation for export.
• Fluorocarbon-free (C0) DWR: a water-repellent treatment without PFC chemistry, increasingly requested by European and North American brands.
• Traceability documentation: fiber certificates and supply chain records that support your own sustainability claims at retail.

Sustainable materials can extend fabric lead time and raise unit cost, so they need to be part of the plan from the first quotation rather than a last-minute substitution. Ask the factory to confirm certification documents before you commit to a sustainable fabric, and request swatches to verify the hand feel is what your design team expects.

MOQ, Sampling, and Cost Considerations

Fabric selection drives unit price more than any other single decision, so ask for fabric options at two or three price levels in your quotation. Before bulk production, request physical swatches, lab dips for colors, and wash-test or colorfastness reports for the chosen fabric, then confirm everything against the pre-production sample. These steps are standard practice and protect both sides of the partnership.
