Case Study: Custom Jacket Zipper Slider for a Railway Operator in Austria

Jacket Zipper Slider for a Railway Operator in Austria

A Railway Operator approached us with a jacket zipper slider requirement for Austria. 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
• Suppliers who disappear once the deposit is paid
• Minimum order quantities far above what a growing brand can absorb

What we specified

How it was resolved

1. We rebuilt the tech pack around Neoprene and locked shrinkage allowance before grading.
2. Decoration was moved to Stone Wash after strike-off tests showed better wash durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and size ratio specification.

Result

• 1,200 pieces delivered inside the 6-week window.
• Unit cost held within 4.5% 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

Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
