Hoodie Manufacturing Process

Hoodies carry more construction than most other jersey garments in normal production. The body follows the same logic as a crew-neck sweatshirt, so this page concentrates on what is different: building the hood, setting the pocket, handling a zip through ribbed edges, and the checks that catch the faults specific to each.

Fabric: the same families, different consequences

Hoodies use the same fabric families as sweatshirts: French terry for lighter, more breathable garments and brushed three-thread fleece for the classic weight, compared in detail in French terry and brushed fleece. What changes is that a hoodie has a hood, which doubles the fabric in that area, and often a lined hood, which doubles it again. Weight therefore compounds: the difference between a 300 and a 400 g/m² fleece is felt far more in a hooded garment than in a crew neck.

Where a hoodie is being developed for a streetwear brand, proportion and fabric quality do more for perceived value than weight alone. That commercial argument is set out in the streetwear sourcing guide. Merch, promotional textiles, corporate wear and workwear programmes for hoodies are covered on the hoodie and sweatshirt manufacturer page.

Building the hood

The hood is assembled as its own sub-assembly before it reaches the body, and its construction is a specification decision rather than a factory default. The panel options and their effect on hood shape are compared in hood construction.

• Two-panel hood. Two mirrored panels joined by a centre seam running over the crown. Simple, economical, and the seam is visible from behind.
• Three-panel hood. Two side panels and a centre gusset panel. It gives a rounder shape that sits better on the head, and it is the more considered construction.
• Lined or double-layer hood. A second layer inside, in the same fabric or a contrast. It gives the hood structure so it stands rather than collapsing, adds warmth, and creates a clean inside face. It also doubles the fabric consumption for that component.
• Unlined hood with a folded edge. Lighter and cheaper, common on French terry styles.

Hood depth and height are measurements that belong in the tech pack, because they decide whether the hood frames the face or swallows it. On oversized styles they are often deliberately increased, and that change has to be graded across sizes rather than applied as one value.

Drawcords and eyelets

The drawcord runs through the hood opening, exiting through two eyelets at the front. Small decisions here are visible on every garment.

• Eyelet type. Metal eyelets are the traditional solution and need to be set cleanly through both hood layers. Stitched buttonholes are an alternative that avoids metal entirely, which some programmes require.
• Eyelet position. Set symmetrically either side of centre front, at a stated distance apart and from the hood edge.
• Cord specification. Width, construction, colour and whether the ends are tipped with metal or plastic, or simply knotted.
• Cord length. Specify it, and check that both ends hang equally when the garment is finished. Uneven cord ends are one of the most common finishing faults on hoodies.

The kangaroo pocket

A front pouch pocket is built as a separate piece and attached to the body panel, usually before the side seams are closed. Three specification points decide whether it looks right and survives use.

• Placement. Measured from the bottom hem and from centre front. Two hoodies with identical measurements everywhere else read differently if the pocket sits 15 mm higher.
• Opening angle and finish. The diagonal opening is usually reinforced, often with a bartack at each end, because that is where the pocket takes stress from hands and phones.
• Pocket bag construction. Whether the pocket is a single applied panel or has a separate bag, and how the bottom edge is caught into the waistband.

On zip styles the pouch becomes two separate pockets divided by the closure, which changes the pattern and the reinforcement at the top of each opening.

Zip hoodies: what changes

Adding a zip changes more than one operation. The front becomes two panels, the hood is built to meet the closure cleanly at the neckline, the waistband is interrupted, and the pockets are split. The zip itself becomes a component decision.

• Zip type and length. Usually an open-ended zip running the full front. Length is graded with the body, so it is ordered per size.
• Tape colour and teeth finish. Both are visible when the garment is worn open, and both can be specified or branded.
• Puller. A standard puller, a custom moulded puller or a cord pull. A custom puller is one of the cheapest ways to make a garment feel specified rather than generic.
• Facing or placket. Whether the zip is set into a facing that hides the tape from inside.
• Chin guard. A small piece at the top of the zip that stops the slider touching the skin.

Alignment is the risk. The zip must run straight, the two front halves must meet level at the hem, and the waistband and pocket openings must match across the closure. It is checked with the garment zipped and lying flat.

Decoration and when it happens

Large chest and back prints go on the flat panel before assembly. This matters more on a hoodie than on a tee, because a finished hoodie has a hood, a pocket and ribs in the way, and pressing evenly through those layers is difficult.

• Screen printing on panels. The standard for bold graphics at volume. On brushed fleece the nap absorbs ink, so solid artwork reproduces better than fine line work.
• Transfer printing, including DTF. For photographic or multi-colour designs, and for smaller placements on finished garments.
• Embroidery. Chest and sleeve positions are worked on panels with backing chosen for the fabric. Embroidering through a completed hood or across a pocket edge is avoided because the layers distort.
• Raised and embossed effects. Tonal branding that suits heavy fleece, run with specialist partners where the fabric and artwork allow.
• Appliqué. A stitched fabric piece, durable and effective at large scale on heavyweight garments.
• Printed neck labels, custom drawcords and zip pullers. Branding through components rather than decoration, the same approach used on tracksuits.

Assembly sequence

1. 1Panels are cut with the nap in one direction and bundled by size and colour.
2. 2Chest and back decoration is applied to flat panels.
3. 3The hood is assembled: panels joined, lining attached where used, edge finished, eyelets set.
4. 4The pocket is prepared and attached to the front panel, with the opening reinforced.
5. 5Shoulders are joined and taped.
6. 6Sleeves are set, then side and underarm seams closed.
7. 7The hood is attached to the neckline and the seam is finished, often with a tape that covers it inside.
8. 8Cuffs and waistband are attached; on zip styles the closure is set and the facing finished.
9. 9The drawcord is inserted and cut to length.
10. 10Labels are attached, the garment is trimmed, steamed, measured and inspected.

Quality control: hoodie-specific checks

What to put in a hoodie tech pack

• Fabric: terry or fleece, composition, target GSM with a range, brushed or unbrushed.
• Hood: number of panels, lined or unlined, lining fabric, hood height and depth, edge finish.
• Eyelets: type, material, position and spacing.
• Drawcord: width, construction, tipping and finished length.
• Pocket: type, placement from hem and centre front, opening angle, reinforcement.
• Zip, where used: type, length per size, tape colour, puller and chin guard.
• Rib: structure, depth and elastane content for cuffs and waistband.
• Measurements with tolerances, including hood height and depth.
• Artwork: files, physical size and placement measured from a fixed point.
• Labels: main, size and care, plus back-neck finishing under the hood.
• Colours for body, rib, cord, zip tape and lining.
• Packing: fold, bag, hangtag, carton assortment.

Sampling

Photograph the sample worn as well as flat. A hood only reveals its shape on a head: whether it stands, how it frames the face, and whether the drawcord sits where it should. On oversized styles this is the difference between a considered proportion and a garment that is simply too big.

Ask for the sample in the intended fabric weight, because hood behaviour changes completely between a 280 g/m² terry and a 420 g/m² fleece. A pre-production sample with the actual zip, cord, eyelets and labels is the reference bulk is inspected against, as set out in the sampling guide.

What drives cost

• Fabric weight and hood construction. A lined three-panel hood in heavy fleece is a significant share of the garment's fabric.
• Number of operations. Hood, pocket, zip and rib attachment are each separate steps.
• Trims. Zip, eyelets, cord and custom pullers are components with their own minimums and lead times.
• Decoration. Print colours and placements, or embroidery stitch count.
• Fabric consumption. Oversized patterns and single-direction nap cutting both raise it.
