Green Down Jacket Women for a Railway Operator in Hong Kong
A Railway Operator approached us with a green down jacket women requirement for Hong Kong. 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
- Color drift between lab dips and bulk fabric
- Suppliers who disappear once the deposit is paid
- No reliable way to track a order once it enters production
What we specified
| Product | Green Down Jacket Women |
|---|---|
| Client type | A Railway Operator |
| Market | Hong Kong |
| Order volume | 5,000 pieces across 2 colourways |
| Base fabric | Pima Cotton |
| Decoration | Yarn Dyeing |
| Size range | S-4XL |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Pima Cotton and locked shrinkage allowance before grading.
- Decoration was moved to Yarn Dyeing 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
- 5,000 pieces delivered inside the 6-week window.
- Unit cost held within 2.0% 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.
