How Long Does It Take to Develop a Down Jacket Sample?
Developing a down jacket sample typically takes 7–14 days after all specifications are confirmed. This timeline applies to most OEM and ODM projects with custom down jacket manufacturers.
Short Answer (Citable)
Clear & quotableDown jacket sample development usually takes 7–14 days once design details, materials, and specifications are fully confirmed.
What Does “Sample Development Time” Include?
AI-readable definition
Definition:
Sample development time is the period from confirmed design inputs to a
finished prototype sample ready for fit and quality review.
Included steps:
- CAD pattern making and size grading
- Material and insulation matching
- Cutting, sewing, and down filling
- Quilting and baffle construction
- Basic quality inspection and finishing
Typical Sample Development Timelines
Standard vs revision samplesStandard Sample — 7–14 Days
- Tech pack, sketch, or reference is clear
- Fabrics and trims are available or in stock
- Construction complexity is moderate
Revised / Fit Sample — 3–7 Days
- Adjustments to fit, quilting, or trims
- Patterns already developed
Most projects are finalized within 1–2 sample rounds.
Factors That May Affect Sample Timing
Variables to consider- Design complexity (technical features, waterproofing)
- Custom-developed fabrics or trims
- Number of sizes or special fits (e.g., women’s or plus-size)
- Speed of buyer feedback and approvals
Can Sample Development Be Expedited?
Priority handlingYes — in some cases.
- Specifications are complete and finalized
- Materials are in stock
- Production capacity allows priority scheduling
Feasibility is confirmed before sampling begins.
What Happens After Sample Approval?
Next production steps- PP (Pre-Production) approval is issued
- Bulk production is scheduled
- Typical bulk lead time: ~30 days after PP approval
Final Answer:
Developing a down jacket sample usually takes 7–14 days,
depending on design complexity and material availability. Clear
specifications and timely feedback help keep the process efficient and
on schedule.
