Custom Raincoat Manufacturer: Waterproof Fabrics and MOQ
By Weavnora · Updated
Direct answer
What buyers need to know
Custom raincoat manufacturer programs usually use a PU-coated, laminated or rubberised shell of about 90–250 GSM rated roughly 3,000–20,000 mm waterproof, with taped or welded seams and a PFAS-free water-repellent finish. Brand MOQs often run 200–500 pcs per style, with 10–20 days per sample and 35–55 days for bulk.

A raincoat has one job, and customers notice immediately if it fails. Yet many rainwear programs go wrong not because the fabric leaks, but because water gets in through seams, zips, pockets or the hood. This guide explains the numbers a rainwear factory will talk about, what they mean in daily use, and how to turn them into a specification you can approve with confidence.
What is a custom raincoat manufacturer?
A custom raincoat manufacturer is an outerwear factory that makes waterproof coats and jackets from coated, laminated or rubberised fabrics to a brand's own design, colours and branding, including seam sealing and weather-proof details. Typical programs use shells of about 90–250 GSM rated roughly 3,000–20,000 mm, start at 200–500 pcs per style and deliver bulk in about 35–55 days after sample approval.
Rating 1: What does a hydrostatic head number mean?
The hydrostatic head, written in millimetres, measures how much water pressure a fabric withstands before water passes through. A higher number means more protection under pressure, such as when you sit on a wet bench or carry a backpack. As a planning guide, around 3,000–5,000 mm suits short city use, while 10,000–20,000 mm suits long exposure. Ask the mill for a test report on the finished fabric, and ask whether it was tested new or after washing.
Rating 2: What does breathability mean for a raincoat?
Breathability measures how well moisture vapour from the body escapes. A PVC or rubberised coat is fully waterproof but does not breathe, so it suits short wear and fashion styles. PU-coated fabrics breathe a little, and laminated membranes breathe more. If your customer walks or cycles in the rain, breathability matters as much as waterproofing. For snow sports and technical builds, our custom ski jacket manufacturer guide covers membranes in more depth.
Rating 3: Why do seams and openings matter most?
Every needle hole is a leak path. Fully waterproof raincoats have taped seams, where a heat-applied tape covers the stitching, or welded seams with no stitching at all. Zips should be water-resistant or covered with a storm flap. Pockets need flaps or water-resistant zips, and the hood should have a peak and adjusters. Write each of these details into the tech pack, because a quote for a "waterproof jacket" without seam sealing is not comparable to one with full taping.
Coated vs laminated raincoat fabric: which option fits?
Most brands choose between a coated fabric and a laminated fabric. The table compares them on practical selection criteria.
| Selection criteria | PU or PVC coated fabric | Laminated membrane fabric |
|---|---|---|
| Waterproof level | Medium to high | High |
| Breathability | Low to medium | Medium to high |
| Handfeel | Firmer, can feel rubbery | Softer, lighter |
| Cost | Lower | Higher |
| Best for | Fashion, city, kids, workwear | Outdoor, cycling, commuter |
| Main risk | Coating peel after washing | Delamination if poorly bonded |
The trade-offs are cost against comfort. A coated fabric is a strong choice for fashion and urban raincoats with short wear time. A laminated fabric suits customers who wear the coat for hours. Many brands offer one of each at different price points.
Which water-repellent finish should you specify?
The outside of most raincoats has a durable water repellent finish, so water beads and rolls off. Older finishes often used PFAS chemistry, which several markets are restricting. Ask your factory for PFAS-free options and test reports, and check how the finish performs after washing. Our PFAS-free apparel sourcing guide explains what to request from mills. If you use recycled polyester or nylon shells, see our recycled polyester clothing manufacturer guide.
How do styles change the build?
Raincoat styles range from short hooded rain jackets to long trench-style macs and ponchos. Long coats need more fabric and longer seams to tape, which raises cost. A fashion mac may use a bonded cotton look, while a commuter jacket may add reflective details, vents and a two-way zip. For a classic double-breasted coat in gabardine rather than a waterproof shell, see our custom trench coat manufacturer guide.
How do you test a raincoat sample?
A simple test plan before bulk:
- Shower test: wear the sample under a shower for 10–15 minutes and check for wet spots inside.
- Seam tape check: inspect tape adhesion at curves, hood seams and underarms.
- Wash test: wash and dry according to your care label, then repeat the shower test.
- Movement test: lift arms, sit and bend to check fit and coverage.
- Hardware check: confirm zips, snaps and adjusters work with wet hands.
How is a raincoat program priced?
Rainwear cost is driven by the shell fabric and its coating or membrane, seam sealing, lining, zips and hardware, design complexity and order quantity. A short unlined jacket in stock coated fabric with stitched seams is the most economical build. Full seam taping adds machine time and tape cost on every seam, and welded construction needs specialist equipment. Two-way water-resistant zips, adjustable hoods, vents and reflective details also add cost. Ask each factory to quote the same specification line by line: fabric composition, weight and waterproof rating, coating or membrane type, seam treatment, zip type, lining and packaging. Without that detail, it is easy to compare a fully taped jacket with a jacket that only has a water-repellent finish.
What does a raincoat production timeline look like?
A typical timeline runs like this:
- Tech pack, fabric and trim selection: about 1–2 weeks.
- Fabric samples and waterproof test reports: about 1–3 weeks.
- First sample: about 10–20 days once fabrics are available.
- Shower, wash and fit tests, then corrections: one or two more rounds.
- Bulk fabric and production: about 35–55 days in total from approval.
Rainwear sells in spring and autumn, so plan backwards from your launch window and leave buffer for custom fabric colours.
Common mistakes in raincoat programs
- Comparing quotes that do not specify seam sealing.
- Choosing a high waterproof rating but leaving zips uncovered.
- Ignoring breathability for active customers.
- Skipping a wash test before approving tape and coating.
- Forgetting to check PFAS rules in your sales markets.
Custom raincoat manufacturer: typical specs and key numbers
| Spec | Typical estimate range |
|---|---|
| Shell fabric weight (coated or laminated) | 90–250 GSM |
| Waterproof rating (hydrostatic head) | 3,000–20,000 mm |
| Seam tape width | 1.3–2.5 cm |
| MOQ per style (brand programs) | 200–500 pcs |

| Bulk lead time after approval | 35–55 days |
| Custom fabric colour lead time | 20–35 days |
| Typical sampling rounds before bulk | 2–3 rounds |
These are typical industry estimate ranges, not quotes; confirm actual figures with your supplier for your fabric, quantity and destination.
Key takeaways
- Waterproof ratings matter, but seams and openings decide real performance.
- Choose coated fabrics for price and laminated fabrics for comfort.
- Specify PFAS-free water repellency and ask for test reports.
- Shower-test and wash-test samples before bulk.
- Compare quotes on identical fabric, rating and seam details.

Buyer questions
Frequently asked questions
How waterproof should a raincoat be?
For city use, a hydrostatic head of about 3,000–5,000 mm is often enough. For long walks and heavy rain, brands usually target 10,000–20,000 mm with fully taped seams. The rating only works if seams, zips and pockets are sealed too.
What is the MOQ for custom raincoats?
Many rainwear factories start at about 200–500 pcs per style. Stock coated fabrics lower the minimum, while custom colours, custom laminates or special seam welding usually raise it.
What is the difference between a coated and a laminated raincoat?
A coated fabric has a waterproof layer applied to the back of the textile, which is usually cheaper. A laminated fabric bonds a separate membrane to the textile, which is often lighter and more breathable but costs more.
Are PFAS-free raincoats possible?
Yes. Many mills now offer PFAS-free water-repellent finishes. They may need reactivation by tumble drying and can perform differently against oily stains, so ask for test results on your exact fabric.
How long does raincoat production take?
Plan roughly 10–20 days per sample round and about 35–55 days of bulk production after approval. Seam taping and custom fabric colours can add time.
