Custom Half Zip Pullover Manufacturing From 100 Units

Sweatshirt And Terry

280–360 GSM brushed fleece suits campus, streetwear, and cold-weather promotional programs; use a relaxed fit and a nylon-coil half zipper with a zipper garage. 240–320 GSM French terry fits spring capsules and premium loungewear. Its loopback interior supports a cleaner regular fit and short metal zipper for mid-tier retail.

Knit And Performance

7–12 gauge knitted quarter-zips target smart-casual customers in autumn and winter. A close-to-body fit, ribbed collar, and fine metal zipper support elevated wholesale or specialty retail. 180–260 GSM performance layers serve golf, travel, and active teams year-round. Use stretch panels, a reverse-coil zipper, and an athletic fit for technical price points.

Shell And Oversized

70–140 GSM wind-resistant shells suit commuting, outdoor events, and transitional weather. A loose layering fit with a coated zipper or storm flap supports functional outerwear assortments. 320–450 GSM oversized styles target fashion-led youth collections in fall and winter. Dropped shoulders, a long half zipper, and heavy rib trims justify higher perceived value.

Fleece And French Terry

280–360 GSM brushed cotton fleece delivers the warmest, softest casual hand for autumn and winter; ring-spun face yarns read more premium than open-end yarns. Cotton-rich fleece can shrink 3–5% unless pre-shrunk and needs care testing for pilling. 240–320 GSM French terry has unbrushed loops, better airflow, and less bulk, making it suitable for spring, layering, and resort deliveries. Its cleaner interior supports a more technical or elevated sportswear perception.

Blends And Performance Fabrics

70/30 or 80/20 cotton-poly fleece improves shape retention, drying speed, and color consistency while lowering cost volatility versus 100% cotton. Polyester content can increase pilling risk, so specify anti-pilling finishing and test high-friction areas. 160–260 GSM polyester performance knits suit training-led styles because they wick and dry quickly, but they can feel less natural and retain odor without an appropriate finish. Use low-heat care instructions and confirm sublimation or transfer compatibility before bulk.

Wool And Knit Structures

280–450 GSM wool blends and fully fashioned knit structures create the highest perceived quality for cool-weather capsules. They require gentler care, can pill at abrasion points, and usually carry longer sourcing lead times than cut-and-sew fleece. 12–7 gauge knit pullovers give progressively denser, warmer structures; ribbed collars and cuffs should be tested for recovery after steaming and wash cycles. Specify fiber percentages rather than relying on generic ‘wool blend’ descriptions.

Silhouette And Component Choices

Three core silhouettes—regular, relaxed, and oversized—need separate body, shoulder, sleeve, and hem measurements; extended sizing requires proportional grading rather than simply scaling a base size. Two zipper options dominate: nylon coil for lighter casual styles and metal teeth for a sharper premium look. Specify quarter-zip length, stand-collar height, zipper pull, rib weight, kangaroo or welt pockets, contrast panels, and color blocking before sampling.

Branding And Pack-Out

One brand system should align tonal embroidery or woven patches with main labels, size labels, wash-care labels, hang tags, and branded polybags or mailers. Two low-visibility choices—matching-thread embroidery and debossed zipper pulls—suit premium minimal collections. Contrast rib stripes, appliqué panels, and printed chest graphics create a more visible sportswear direction.

Choose Decoration By Product

100-unit runs generally favor screen print, embroidery, or heat transfer because setup and application remain controllable. DTG suits highly detailed multicolor art on cotton-rich light garments, while appliqué and woven patches add dimensional premium value. Three placement zones affect longevity: left chest stays readable, back panels carry larger artwork, and sleeves suit narrow marks. Avoid heavy embroidery on lightweight fleece because it can distort the face fabric.

Zipper And Collar Control

A No. 5 nylon-coil zipper suits most midweight fleece; use a metal zipper only when its weight and finish fit the design. Specify the puller, tape color, top stop, and zipper length in millimeters. A finished collar should sit evenly when zipped and lie flat when open. Check that both zipper tapes are centered, equally tensioned, and do not ripple or twist at the collar seam.

• Zip the garment 10 times; movement must stay smooth.
• Compare left and right collar points when fully closed.
• Confirm zipper tape is caught evenly in the seam.

Seams, Ribs, And Stability

Eight to 10 stitches per inch is a practical benchmark for regular construction seams, while high-stress joins benefit from consistent seam allowance and reinforcement. Inspect shoulder seams, underarms, pocket corners, and the zipper base for skipped stitches or loose thread. A rib cuff should recover after repeated stretching rather than remain expanded. Require a fabric-stability test after washing, because torque, shrinkage, and spirality can distort side seams and zipper alignment.

• Stretch cuffs and hem, then check recovery after 30 seconds.
• Measure chest, body length, and sleeve length before and after washing.
• Turn seams inside out to inspect reinforcement consistency.

Grading And Wash Approval

XS through 3XL requires intentional grading, not a uniformly enlarged base pattern. Review shoulder width, sleeve length, body sweep, and collar circumference across the size set before bulk approval. Three wash cycles using the agreed care method reveal many early failures in color, shape, print adhesion, and zipper performance. Retain the sealed pre-production sample, measurement chart, and wash results as the repeat-order control standard.

• Measure at defined points with the garment laid flat.
• Use approved tolerances for every size and critical point.
• Inspect random packed units against the sealed sample.

Verify Category Capability

2 completed half-zip samples should be requested before development payment: inspect collar stand shape, zipper placket balance, rib recovery, and inside seam finishing. 1 factory visit, live video walkthrough, or production-line proof can reveal whether the supplier cuts, sews, decorates, and packs in-house or relays orders through a trading office.

• Which zipper brands and puller options have you produced?
• Can you show size-set and bulk inspection records?
• Which operations are subcontracted, if any?

Test Development Control

1 pre-production process should include tech-pack review, fabric swatches, pattern creation, prototype, revision notes, graded size set, and final approval. Factories that only copy a reference garment often miss collar geometry and grading tolerances. 3 questions expose development discipline: Who owns the pattern? What measurement tolerances apply? How are comments documented between sample rounds?

Confirm Commercial Readiness

80,000-plus monthly units may suit ongoing programs, while 100-unit production can support launches; ask how capacity is reserved during peak seasons. Confirm quoted sample, bulk, and shipping lead times separately. 3 compliance checks matter before placing an order: request applicable OEKO-TEX, GOTS, WRAP, or BSCI documentation; verify export destination experience; and confirm final inspection and balance-before-shipment procedures.

Fabric And Shrinkage Shortcuts

280 GSM alone does not define warmth, recovery, or surface quality; fiber blend, yarn, loop structure, and brushing matter. Request a swatch, wash test, and finished-garment hand-feel review. 3–5% wash shrinkage can move body length and sleeve measurements outside tolerance. Specify the wash method, allowable shrinkage, and post-wash measurement chart before bulk cutting.

Zipper And Sample Gaps

YKK, SBS, or an approved equivalent zipper should be named by size, finish, puller, tape color, and stopper configuration. Unspecified hardware can snag, wave at the placket, or vary between production lots. 1 complete pre-production sample must include final fabric, labels, artwork, zipper, and wash. Approving a partial development sample transfers unresolved risks into bulk production.

Fit And Artwork Ambiguity

Six core points—chest, body length, shoulder, sleeve, cuff, and hem—need graded measurements and tolerances. A reference photo without a spec sheet invites inconsistent fit across XS–3XL. Pantone codes, print dimensions, placement from HPS, and artwork files prevent decoration disputes. Match fine gradients to DTG or DTF; use screen print for stable larger-volume solid artwork.

Timeline And Quote Traps

8–12 weeks is a typical planning window once development, material booking, sampling, approvals, and freight are considered. Build a critical path with decision owners, approval dates, and buffer for lab dips or revisions. 3 quotes with different fabric, zipper, inspection, and packing assumptions are not comparable. Normalize the bill of materials and quality checkpoints before selecting a supplier; the lowest quote often omits the controls that prevent claims.

Set The Commercial Brief

One target customer, retail price, and margin target should define the brief before design work starts. State intended channels, launch date, color count, and first-order quantity. A 2.5–4.0 retail-to-landed-cost multiple is a common planning check, not a universal rule. The brand approves the target cost and delivery window; the factory flags feasibility.

• Customer and size range
• Target retail and landed cost
• Colorways and launch quantity

Lock Design And Materials

One annotated sketch or reference garment should identify collar height, half-zip length, pocket layout, rib dimensions, and logo positions. Select fabric weight, composition, color standard, zipper specification, and decoration method. 280–360 GSM French terry suits many transitional pullovers, while brushed fleece changes warmth and bulk. Request swatches before approving bulk fabric.

Build And Review Samples

One tech pack should include measurement points, tolerances, graded size chart, construction callouts, Pantone references, artwork files, labels, and packaging. Junsheen can review manufacturability from a finished pack or early concept. A first prototype tests proportion and make; revisions must be written against dated photos and measurements. Approve a size set for fit across the selling range before production.

Release Bulk With Controls

One pre-production sample must match approved fabric, trims, color, measurements, decoration, labels, and packing before cutting bulk. The brand signs the approval; the factory retains the approved sample and records. AQL level, measurement tolerances, defect definitions, carton marks, Incoterms, destination, and shipping date should be confirmed in writing. Plan final balance and freight booking early enough to protect the launch date.

• Approve pre-production sample
• Confirm inspection standard
• Confirm shipping documents and routing
