Sleeping Bonnet for a Gym Chain in Vietnam
A Gym Chain 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
- Long lead times that miss the selling season
- Color drift between lab dips and bulk fabric
- Suppliers who disappear once the deposit is paid
What we specified
| Product | Sleeping Bonnet |
|---|---|
| Client type | A Gym Chain |
| Market | Vietnam |
| Order volume | 500 pieces across 4 colourways |
| Base fabric | Lambswool |
| Decoration | Glow-in-the-Dark Printing |
| Size range | Custom grading |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Lambswool and locked shrinkage allowance before grading.
- Decoration was moved to Glow-in-the-Dark 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
- 500 pieces delivered inside the 10-week window.
- Unit cost held within 2.0% 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
Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
