Case Study: Custom Green Down Jacket Women for a Marathon Organizer in Japan
Green Down Jacket Women for a Marathon Organizer in Japan
A Marathon Organizer approached us with a green down jacket women requirement for Japan. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Packaging that arrives crushed and unsellable
- Unclear responsibility when a defect shows up after washing
- Minimum order quantities far above what a growing brand can absorb

What we specified
| Product | Green Down Jacket Women |
|---|---|
| Client type | A Marathon Organizer |
| Market | Japan |
| Order volume | 2,000 pieces across 4 colourways |
| Base fabric | Oxford |
| Decoration | Screen Printing |
| Size range | S-4XL |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Oxford and locked shrinkage allowance before grading.
- Decoration was moved to Screen Printing after strike-off tests showed better wash durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and size ratio specification.

Result
- 2,000 pieces delivered inside the 5-week window.
- Unit cost held within 4.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
