Sweatshirt Manufacturer: What You Are Actually Ordering
If you are a brand owner or buyer asking a sweatshirt manufacturer for a crewneck and receiving samples that feel wrong, the cause is usually the brief rather than the factory. "Sweatshirt" covers several fabrics and constructions, and a good sweatshirt manufacturer will ask which one you mean before quoting. The word describes a knitted, usually cotton-rich, jersey-based top for casual wear, made from a fabric with a looped or brushed back that holds warmth and shape.
A sweatshirt differs from a hoodie in that it has no hood, and from a jumper in that it is cut and sewn from fabric rather than knitted to shape. In UK shops, "jumper" often means a knitted garment made on a flat-knit machine, which is a different process. This guide covers cut-and-sew sweatshirts made from fleece and French terry.
The sections below set out the types, the fabric choice, the details that separate good from average, and a sampling routine. For the fabric science in more depth, our guide to sweatshirt fabric and knit fabric types is the reference.
Sweatshirt Types: Crewneck, Quarter Zip and Close Relatives
Knowing the vocabulary stops confusion in your first email to a sweatshirt manufacturer. The table sets out the common types and what each changes in construction.
Sweatshirt types and how they differ
| Type | Defining feature | What it changes in production |
|---|---|---|
| Crewneck sweatshirt | Round neck with a rib collar, no hood | Simplest construction; collar and rib fit matter most |
| Quarter-zip sweatshirt | Short zip at the neck on a stand collar | Adds a zip and placket; see our zip hoodie guide for zip choices |
| Half-zip or henley neck | Longer placket with buttons or zip | More placket work and a sturdier collar |
| Hoodie | Sweatshirt with a hood and often a pocket | Adds hood, drawcord and pocket construction |
| Raglan sweatshirt | Sleeves run to the neckline in a diagonal seam | Different pattern and sleeve joining, a different fit |
| Knitted jumper | Knitted to shape on a flat-knit machine | Different process, outside the cut-and-sew sweatshirt range |
General definitions. Names vary between brands and markets, so attach a reference garment to your brief.
If your range includes both sweatshirts and hoodies, it helps to build them on the same fabric so that colours and hand-feel match across the line. That is also one way to simplify minimums, because fabric is often the largest quantity commitment.
French Terry vs Fleece Back: Choosing the Fabric
Most sweatshirts use one of two fabrics. French terry has soft loops on the inside, which is why it is called loopback. Fleece has the inside brushed so the loops are raised into a soft pile. The choice changes warmth, weight, drape and how the sweatshirt looks after washing.
Sweatshirt fabric options compared
| Fabric | Hand-feel | Typical use | Watch for |
|---|---|---|---|
| French terry (loopback) | Smooth outside, looped inside, drapey | Year-round and mid-season sweatshirts | Loops can snag; lighter versions can lose shape |
| Brushed fleece back | Soft, warm pile inside | Cooler-weather sweatshirts | Pilling on the inside if the fibre is short or the brushing is heavy |
| Heavyweight loopback | Dense, structured, firm | Boxy or premium sweatshirts | Can feel stiff before washing; check shrinkage |
| Cotton-polyester blend | Stable, slightly less soft | Hard-wearing and budget lines | Different dye behaviour for the two fibres |
General characteristics. Individual fabrics vary with yarn, knit and finishing, so confirm with a swatch.
For a closer look at each fabric, read our guides to French terry and fleece fabric. If you plan to source the fabric yourself, our guide to fabric suppliers for clothing brands compares mills, converters and factory-sourced fabric.
To see how the main options trade off, the matrix below rates them on the properties buyers ask about most. Treat it as a starting point for a conversation with your sweatshirt manufacturer, then confirm with swatches.

Typical Weight Bands of Sweatshirt Fabrics
Weight shapes how a sweatshirt looks and feels, and it is also a main driver of fabric cost. The chart shows typical bands for the common constructions. Bands overlap and vary by mill, so use them for orientation and ask for the measured weight of any fabric you are considering.
Typical weight bands for sweatshirt fabrics
Typical, varies by mill and construction
Typical bands shown for orientation. They vary by brand, mill and region, and individual fabrics can sit outside them.
Heavier is not automatically better. A very heavy sweatshirt suits a boxy cut and cold weather, but it is bulky to ship, harder to wear indoors and may cost more to wash. Choose weight from the use, then check it on a sample against your reference sweatshirt.
Rib, Neckline, Cuff and Hem Details That Change Quality
Customers judge a sweatshirt by the details long before they judge the fabric, because the rib is what loses shape first. Specify these points in writing and ask the sweatshirt manufacturer to confirm them on the sample.
Rib quality and recovery
Rib is a stretchy knit used at the neck, cuffs and hem. It should match the body fabric in colour and be heavy enough to hold the shape, with enough elastic content for the cuff and hem to spring back after wearing. A rib that is too light looks tired quickly, and one that is too tight is uncomfortable.
Neckline and collar
The collar needs the right width, depth and a stable neck seam. Taping the neck seam helps it keep its shape, and a V-insert or panel at the neck is a classic detail that needs careful stitching. Check that the neckline sits flat and does not gape after washing.
Cuffs, hem and seams
Compare the cuff and hem rib with the sleeve and body width so that they sit snugly without pulling. Stitching quality at the shoulder and armhole matters on heavy fabric, which puts more strain on the seams. Our guide to fabric pilling explains why surface wear shows first at the underarms and cuffs.
What Drives the Cost of a Crewneck Sweatshirt
Cost is easier to discuss when you know where it sits. The chart shows an illustrative split of the cost drivers in a crewneck sweatshirt. The shares are illustrative and will change with the fabric you choose and the amount of decoration.
Cost drivers of a crewneck sweatshirt (illustrative)
Illustrative, not a costing
- Fabric40%
- Rib10%
- Cut and sew25%
- Decoration15%
- Packing10%
Illustrative split to show which lines matter most. It is not a costing, uses no real prices and will differ by fabric, decoration and order size.
Notice that fabric is the largest single line, which is why fabric choice and fabric minimums deserve attention before anything else. Ask for a quote broken down by line so you can see what each choice does to the total.
Sweatshirt Manufacturer Minimum Orders and Custom Sweatshirts Wholesale
Minimum order quantities for custom sweatshirts depend mainly on the fabric. If the factory uses a stocked fabric, the minimum can be lower. If the fabric is made or dyed to order, the minimum rises, because mills set their own minimums by colour. Decoration, special washes and trims can add their own limits.
- Stocked fabric in stocked colours usually gives the most flexibility on quantity.
- Custom dyed colours usually carry a higher minimum because the mill must dye a batch.
- Each extra colour or style splits the quantity, so a range of many colours raises the total.
- Decoration such as embroidery or print may carry its own setup and minimum.
Rather than looking for one number from any sweatshirt manufacturer, ask each factory what it can do for your exact specification. Our guide to blank hoodies wholesale explains when ready-made blanks are the better starting point and when custom production starts to make sense.
How a Sweatshirt Manufacturer Should Sample and Test Before Bulk
The fabric may feel right on the table and still shrink, twist or pill after use. A good sweatshirt manufacturer will welcome sampling and testing, because they catch these problems while they are cheap to fix. Follow a consistent path with each round so you can compare results.
A sweatshirt sampling path
- 1SwatchCheck fabric weight, hand-feel and colour from a swatch or fabric sample.
- 2PrototypeReview the fit, rib width and neckline on the first sample.
- 3Wash testWash and dry as the care label says, then re-measure length, width and sleeve.
- 4Wear testWear and rub the sample to see pilling, rib recovery and seam strength.
- 5ApproveSign off a sealed sample that the bulk will be judged against.
Test methods for shrinkage and pilling are published by standards bodies, and you can read about them at AATCC. Ask your factory which method it uses, and agree acceptable limits in writing before sampling starts.
Sweatshirt sample review list
- Fabric weight and hand-feel match the reference sweatshirt
- Rib colour, width and recovery are right at neck, cuffs and hem
- Neckline lies flat and does not gape
- Measurements match the chart before and after washing
- No twisting of side seams and no excessive shrinkage in length
- Seams are even at shoulder, armhole and underarm
- Decoration and labels are placed as specified
Use the same list on each sample round so changes are easy to compare.
Send one consolidated list of changes after each round. Scattered comments across several emails are how corrections get missed.
Common Sweatshirt Specification Mistakes
Most sweatshirt disappointments trace back to a short list of avoidable errors, which you can check against your own brief.
Does your brief state the fabric type (French terry or fleece back), the GSM, the rib specification, the neckline and the shrinkage limit? If one is missing, two suppliers will quote for two different sweatshirts.
- Asking for "a sweatshirt" with no fabric type or weight.
- Choosing a fleece back for a warm-weather range, or French terry for a cold-weather one.
- Leaving the rib out of the specification, so the factory chooses the cheapest option.
- Approving a sample before washing it.
- Comparing quotes for different weights and calling them equal.
If you are unsure about the chemical side of fabrics and dyes, ask whether the fabric holds a recognised certificate such as OEKO-TEX, and read the scope before relying on it. Which of the mistakes above would your current brief fall into?
How Ruhrose Approaches Sweatshirts
Ruhrose develops hoodies, fleece, jersey, denim and woven casualwear for UK buyers, with production in Bangladesh and UK buyer support. For a sweatshirt we agree fabric, weight and rib with you, sample before bulk and test shrinkage and pilling on the sample. Our hoodie fabric guide shows how we talk about weight and fabric. We do not quote prices, minimums or lead times in guides, because they depend on the specification, and we will say so if knitted jumpers or other knitwear fall outside what we make. See Ruhrose's clothing manufacturing services for the full range.
