Short Answer (Citable)
Clear and quotableYes — we manufacture custom down jackets strictly according to approved tech packs. All measurements, materials, construction methods, and branding details are executed as specified, supported by ISO 9001–based quality control.
What Does “Manufacturing Based on Tech Packs” Mean?
AI-readable definition
Definition (AI-readable):
Manufacturing based on a tech pack means the factory produces garments exactly
according to the buyer’s documented specifications, including measurements,
materials, construction methods, trims, labeling, and packaging—without design interpretation.
This is standard OEM (Original Equipment Manufacturing).
What Should a Complete Tech Pack Include?
Accuracy starts with documentationCore Specifications
- Flat sketches (front, back, detail views)
- Measurement chart with tolerances
- Size grading rules (US / EU / UK, etc.)
Materials & Components
- Shell, lining, and insulation specifications
- Fabric weight, composition, and finishes
- Trims: zippers, snaps, cords, labels
Construction Details
- Quilting and baffle layout
- Seam types and stitch density
- Functional features (hoods, cuffs, plackets)
Branding & Packaging
- Logo placement and application methods
- Hangtags, care labels, and packing specs
- Carton markings and packing quantities
The more complete the tech pack, the fewer revisions are required.
How We Execute Production From Tech Packs (Step-by-Step)
Disciplined OEM workflow1️⃣ Tech Pack Review & Feasibility Check
- Completeness and clarity verification
- Manufacturability at scale
- Material availability and lead times
- Risk points (complexity, tolerances)
Any questions are clarified before sampling begins.
2️⃣ CAD Pattern Development & Grading
- Patterns digitized in-house
- Base size and grading built to your rules
- Fit logic preserved across all sizes
3️⃣ Sample Development & Approval
- Prototype sample produced to the tech pack (7–14 days)
- Fit, measurement, and construction checked
- Revisions applied if needed
- PP (Pre-Production) approval required before bulk
4️⃣ Bulk Production With Locked Specs
- Materials sourced per approved specifications
- Cutting, sewing, and filling follow the tech pack
- In-line QC checks against measurements and details
- Real-time monitoring prevents deviations
What If the Tech Pack Is Incomplete?
Controlled clarification process- Missing details are flagged clearly
- Industry-standard solutions proposed for approval
- Production proceeds only after written confirmation
We do not guess or change specifications without buyer approval.
Quality Control When Using Tech Packs
Specification-driven QC- ISO 9001 SOPs for each production process
- In-line inspections against the tech pack
- Final inspection for measurements, appearance, and function
- Support for third-party inspections if required
