Custom Waterproof Jacket Development: Fabric, Seam Sealing, Zippers & Tech Pack Checklist
An RFQ-ready checklist for custom waterproof jacket development covering fabric, seams, zippers, hood, fit, branding and approval.
Custom Waterproof Jacket Development: Fabric, Seam Sealing, Zippers & Tech Pack Checklist
Answer first
A custom waterproof jacket brief should define intended use, shell construction, fabric or membrane concept, water and breathability requirements, seam sealing, zippers, hood, ventilation, pockets, cuffs, hem, fit, size range, colors, branding, quantity and reference files. Fabric performance is only one input: the finished garment also depends on seams, closures, panel layout and assembly. Validate these details in a sample before bulk.
RFQ checklist
Product type and intended use; shell construction; fabric or reference fabric; waterproof requirement; breathability requirement; seam sealing; zipper direction; hood; ventilation; pockets; cuffs; hem; fit; size range; colors; logos/artwork; quantity; Tech Pack, images or reference garment.
Key Takeaways
- Separate fabric performance from finished-garment construction.
- Include seams, zippers, hood, pockets and fit in the brief.
- Sample approval should cover construction, closures, branding and measurements.
- Partial project information is enough to start a review.
What the factory needs to review
Explain the weather use and target wearer, then define construction priorities. If the design uses a membrane, coating or DWR concept, identify it as part of the brief without inventing a numerical rating. Show seam treatment, zipper and pocket details clearly.
Sampling and bulk approval
The sample should validate fabric handfeel, fit, hood, cuffs, hem, seam treatment, zippers, ventilation, pocket access, branding and overall appearance. Record changes and approve the final reference before bulk. Flexible MOQ — typically starting from 100 pcs per style, depending on product design, fabric, color, trims and customization.
FAQs
Does waterproof fabric automatically make the finished jacket waterproof? No. Seams, closures and construction must also be reviewed.
Can I start from reference images? Yes. Images, a reference garment, sketch, measurements or Tech Pack can support an initial project review.
What should be checked in the sample? Fit, materials, seam treatment, zippers, hood, pockets, cuffs, hem, branding and measurements.
What should be approved before bulk? Approve the reference sample and confirmed production specification.
