Inside Boys Swim Trunk for a Surf School in Belgium
A Surf School approached us with a inside boys swim trunk requirement for Belgium. 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
- Packaging that arrives crushed and unsellable
- Color drift between lab dips and bulk fabric
What we specified
| Product | Inside Boys Swim Trunk |
|---|---|
| Client type | A Surf School |
| Market | Belgium |
| Order volume | 5,000 pieces across 3 colourways |
| Base fabric | Recycled Nylon |
| Decoration | Seam Sealing |
| 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 Recycled Nylon and locked shrinkage allowance before grading.
- Decoration was moved to Seam Sealing 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 10-week window.
- Unit cost held within 3.0% 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
Approve a pre-production sample from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
