Case Study: Custom Sleeping Bonnet for a Promotional Products Company in Vietnam
Sleeping Bonnet for a Promotional Products Company in Vietnam
A Promotional Products Company approached us with a sleeping bonnet requirement for Vietnam. 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
- Inconsistent sizing between production runs
- No reliable way to track a order once it enters production
- Unclear responsibility when a defect shows up after washing

What we specified
| Product | Sleeping Bonnet |
|---|---|
| Client type | A Promotional Products Company |
| Market | Vietnam |
| Order volume | 5,000 pieces across 4 colourways |
| Base fabric | Elastane Blend |
| Decoration | Smocking |
| Size range | Custom grading |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Elastane Blend and locked shrinkage allowance before grading.
- Decoration was moved to Smocking 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.
