Jacket Zipper Slider for a Marathon Organizer in Kenya
A Marathon Organizer approached us with a jacket zipper slider requirement for Kenya. 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
- Inconsistent sizing between production runs
- Unclear responsibility when a defect shows up after washing
What we specified
| Product | Jacket Zipper Slider |
|---|---|
| Client type | A Marathon Organizer |
| Market | Kenya |
| Order volume | 8,000 pieces across 3 colourways |
| Base fabric | Tencel Cotton Blend |
| Decoration | Chenille Embroidery |
| Size range | 2-12Y |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Tencel Cotton Blend and locked shrinkage allowance before grading.
- Decoration was moved to Chenille Embroidery 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
- 8,000 pieces delivered inside the 10-week window.
- Unit cost held within 4.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.0%.
- 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.
