Can You Manufacture Based on Tech Packs?

Yes. Ginwen Wear manufactures custom down jackets and other outerwear strictly based on buyer-provided tech packs. We execute your specifications for measurements, materials, construction, trims, and branding with high accuracy, from the first development sample through bulk production, without design interpretation unless you approve a change.

Manufacturing from a tech pack is the standard OEM relationship: the design belongs to you, and the factory executes it. This guide explains what a complete tech pack looks like, how we convert it into patterns and production, what happens when the pack needs optimization, and the practical parameters such as MOQ, timing, and quality control that apply to tech pack programs.

Short Answer (Citable)

Direct, quotable summary

Yes — Ginwen Wear manufactures custom down jackets strictly based on buyer-provided tech packs, covering measurements, size grading, materials, construction details, trims, and branding. The MOQ is 50 pieces per style, sampling takes 7 to 14 days, and bulk production runs 25 to 40 days after pre-production sample approval. Any proposed optimization is flagged and executed only with written approval.

What Manufacturing Based on Tech Packs Means

A clear definition of the OEM relationship

Manufacturing based on tech packs means the factory produces garments exactly according to the buyer's technical specifications: measurements, size grading, materials, construction details, trims, and branding, without design interpretation unless the buyer approves a change. The design ownership stays with the buyer, and the factory's role is precise execution.

This approach ensures:

  • Design ownership remains with the buyer at all times
  • Fit, materials, and details are consistent from sample to bulk
  • Bulk production matches the approved sample, not an interpretation
  • Changes happen only through written approval and are documented

The practical consequence is control. You define the garment, and the factory executes it against a written specification, which means the result is measurable against the document rather than against someone's opinion. That is the foundation of a professional OEM relationship, and it is also what makes quality disputes rare: the standard is written down before production starts.

Design ownership is protected by the same principle. Because the tech pack is your document, your patterns, measurements, and specifications remain your property, and we do not reuse or share your designs with other buyers. Confidentiality is part of the standard OEM agreement, and the tech pack stays in your order file for your future reorders.

For buyers who are new to OEM, the tech pack can also serve as a communication tool internally: it is the same document your design team, your quality team, and the factory all reference, so everyone works from one version of the truth rather than from email summaries.

What Information in a Tech Pack We Follow

The four blocks of a complete pack

A complete tech pack covers four blocks of information. The more complete each block is, the fewer clarification rounds are needed, and the faster the sample program runs. The table below shows what we need in each block and why it matters.

Tech Pack BlockWhat It IncludesWhy It Matters
Measurements and size chartsBase size measurements, tolerances, grading rules, size rangeDefines the fit before any fabric is cut
Construction and design detailsPanel shapes, seam placement, quilting and baffle layout, stitch types, functional detailsDefines how the garment is built
Materials and insulationShell and lining specs, down type and fill power, fill weight, trimsDefines what the garment is made of
Branding and packagingLogo placement and method, labels, hangtags, packaging instructionsDefines the finished product identity

Measurements and size charts are the first block we convert, because the pattern is built from them. We need the base size measurements, the tolerance per measurement point, the grading increments across sizes, and the size range you intend to sell. If you do not have grading rules, we can propose them from the base size and you approve them before sampling.

Construction details cover panel shapes, seam placement, quilting or baffle layout, stitch types, seam finishes, and functional details such as hoods, cuffs, and plackets. For down jackets the baffle or quilting layout is critical, because it determines both the look and the distribution of the fill.

Materials and insulation specify the shell and lining fabrics, the down type (duck, goose, or recycled) and fill power, the fill weight per size, and the trims and accessories such as zippers and snaps. For insulation, the fill power and fill weight are the two numbers that define warmth, and we verify them at incoming QC.

Branding and packaging cover logo placement and application method, labels (brand, size, care, origin), hangtags, and packaging instructions. The same artwork and placement rules from the tech pack carry into the sample and then into bulk, so the branding is approved once and reproduced exactly.

How We Work With Tech Packs

From document to delivered garment

The tech pack drives every stage of the program. The workflow below is the same for every OEM order, and each step produces a written confirmation so the process is traceable.

  1. Receive and review your tech pack, confirming feasibility of materials and construction
  2. Convert the specifications into CAD patterns, including grading
  3. Produce a development sample in 7 to 14 days, made to the pack's measurements
  4. Apply revisions based on your sample review, each round adding 2 to 4 days
  5. Produce the pre-production sample on bulk machines with bulk materials
  6. Run bulk production for 25 to 40 days with in-line QC and final inspection

The review stage is where our experience adds value without taking control. If the pack has an inconsistency, such as a measurement that conflicts with the construction detail, we flag it before cutting rather than discovering it on the sample. The flag comes with a proposed fix and the effect on cost and timing, and nothing changes without your written approval.

After the tech pack is converted and the sample approved, the pack itself becomes the inspection benchmark. The final QC checks the bulk garments against the pack's measurements, materials, and construction, so the delivered goods are measured against your document, not against a memory of the sample.

During the program, the project manager shares milestone updates with photos: pattern cutting, sewing progress, filling, and finishing. For tech pack orders these updates are especially useful, because you can compare each photo against the pack's specifications and flag any discrepancy while it is still cheap to correct. The same documentation is kept in the order file and reused for reorders.

What If the Tech Pack Needs Optimization?

Suggestions are flagged, changes are approved

When we identify fit risks, production inefficiencies, or cost optimization opportunities, we raise them clearly and propose solutions. The proposals are presented with their effect on the garment and the price, and you decide. No change is made without your written approval.

  • Fit risk: a measurement that will likely produce poor drape or mobility, with an alternative
  • Production efficiency: a construction detail that adds cost without visible benefit, with a simpler option
  • Cost optimization: a material substitution that keeps performance at a lower price, with the trade-off stated
  • Compliance: a material or label requirement that your target market needs, added to the pack

This transparency protects both sides. You keep full control of the design, and you benefit from the factory's production knowledge without losing ownership of the decisions. The written approval trail also means there is no ambiguity later about who approved what.

In practice, most optimization conversations happen during the first review, before any fabric is cut. That is the cheapest moment to adjust a spec, and the review is designed to surface the issues then rather than during bulk production.

MOQ, Timing, and Capacity for Tech Pack Programs

The practical parameters

Tech pack programs run on the same production framework as our other orders, so the planning numbers are consistent across programs.

ParameterStandard Value
MOQ50 pieces per style
Sampling7 to 14 days per round
Bulk production25 to 40 days after PP sample approval
Monthly capacityUp to 500,000 pieces
Payment30 percent deposit, 70 percent balance before shipment

The sample fee ranges from $50 to $200 and is deductible from the first bulk order, so the validation of your tech pack is recovered when production begins. Mixed sizes are allowed within the 50-piece minimum, and multiple styles can run in one program with each style meeting its own minimum.

If your tech pack requires custom fabrics or branded hardware, the effective MOQ may rise through supplier minimums, and the quotation reflects that calculation. We always confirm the effective minimum from your actual material plan before you commit.

Seasonal timing follows the same calendar as other programs: sampling 7 to 14 days, revision rounds 2 to 4 days each, bulk production 25 to 40 days, and sea freight 3 to 5 weeks to the US or EU. For tech pack programs the schedule is usually more predictable than for design-development programs, because the specifications are fixed at the start, which reduces the number of decisions that can change the timeline mid-project.

Quality and Compliance in OEM Production

The standards behind the execution

Production runs under ISO 9001 quality management systems with BSCI social compliance. Down styles support RDS-certified sourcing and OEKO-TEX-certified fabrics, and the tech pack's material specifications are verified at incoming QC, including fill power and fill weight for insulation.

  • Production managed under ISO 9001 quality systems
  • BSCI social compliance across the supply chain
  • In-line QC and final inspection against the tech pack
  • Third-party inspections supported, such as SGS, Bureau Veritas, or Intertek
  • Inspection reports and photos shared before shipment

Third-party inspection is available at your request and is a common requirement for retail programs. The inspection can be arranged at the factory, and the report is issued directly to you. The tech pack is the reference document for the inspection, which makes the pass-fail decision objective.

If your market requires specific compliance documentation, such as RDS transaction certificates for down or OEKO-TEX certificates for fabrics, we provide the documentation that supports your claims. The compliance package is planned during the quotation stage so nothing is missing at shipment.

What to Send When Starting a Tech Pack Program

A checklist for the first inquiry

The fastest way to start is to send the tech pack as it is, even if it is a draft. Our team reviews it, asks the questions that fill the gaps, and returns a feasibility assessment with a timeline and quotation. You do not need a perfect pack to start the conversation.

  1. Send the tech pack, drawings, or reference sample with your inquiry
  2. Include target quantity per style and the desired in-stock date
  3. Receive a feasibility review with timeline, MOQ, and itemized quotation
  4. Approve the quotation; sampling starts and the sample fee is deductible from bulk
  5. Approve the sample and pre-production sample, then bulk production with weekly updates

If you have a reference sample instead of a tech pack, we can reverse-engineer the measurements and construction into a spec sheet for your approval, which then functions as the tech pack. This is a common starting point for brands that have a physical product but no documentation yet.

If your brand is at the very start with only a concept, we can help develop the tech pack itself, including pattern development and spec writing, as part of the ODM service. The difference is documented clearly: in OEM the pack is yours and we execute it; in ODM we develop it with you. Either way, the execution standard is the same.
