Case Study: Custom Kids Aviator Hat for an Amazon Private Label Seller in Portugal
Kids Aviator Hat for an Amazon Private Label Seller in Portugal
An Amazon Private Label Seller approached us with a kids aviator hat requirement for Portugal. 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
- No reliable way to track a order once it enters production
- Inconsistent sizing between production runs
- Unclear responsibility when a defect shows up after washing

What we specified
| Product | Kids Aviator Hat |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | Portugal |
| Order volume | 2,000 pieces across 3 colourways |
| Base fabric | Moisture-Wicking Knit |
| Decoration | Garment Dyeing |
| Size range | S-4XL |
| Sampling rounds | 4 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Moisture-Wicking Knit and locked shrinkage allowance before grading.
- Decoration was moved to Garment 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
- 2,000 pieces delivered inside the 12-week window.
- Unit cost held within 3.0% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.5%.
- 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.
