300D Polyester Ripstop Fabric – Waterproof TPU Milky Coating in Hi-Vis Yellow (EN ISO 20471 / EN 343 4:4)

For high-quality B2B brands, “hi-vis” is not just a bright color. It’s a repeatable safety requirement that must stay consistent across bulk lots, withstand real wear, and integrate smoothly into certified garment systems. This 300D polyester ripstop Oxford in fluorescent hi-vis yellow is designed as a dependable outer-shell fabric for PPE workwear and rainwear, combining tear-resistant ripstop durability with waterproof + breathable TPU milky bonding.

On the performance side, this construction is listed as Waterproof & Breathable, 10,000mm Water Pressure, RET < 15, and referenced as EN 343 4:4—a combination buyers typically look for when they want both strong rain protection and high comfort in active work environments.

Why Premium B2B Buyers Choose This Fabric

1) Ripstop durability for real workwear abuse

Ripstop structure helps reduce tear propagation if the fabric is punctured—valuable for jobsite garments, rain shells, and protective outerwear that sees repeated snagging, abrasion, and folding. (This product is explicitly listed as 300D ripstop Oxford.)

2) Waterproof + breathable performance you can specify (10,000mm / RET < 15)

The product page states: 10,000mm water pressure and RET < 15.
For buyers, these two numbers translate into:

• Water resistance (hydrostatic head / water pressure rating) for keeping rain out

• Breathability measured via RET (water vapour resistance)—lower RET means better moisture transfer, helping wearers stay drier and more comfortable during movement

3) EN 343 4:4 positioning (rain protection + breathability class)

EN 343 typically expresses performance as X:Y (water penetration resistance class : breathability class). Many industry guides show Class 4 as the highest tier for both waterproofness and breathability (Ret ≤ 15 for breathability class 4).
This product is presented as EN 343 4:4 on the page, matching the listed RET < 15 claim.

4) Hi-vis yellow data support for EN ISO 20471 development

EN ISO 20471 focuses on high-visibility clothing performance and includes requirements for fluorescent background material (color/luminance) as part of the system. Independent test labs describe that background material is assessed for color/luminance performance (including chromaticity & luminance factor) within the EN ISO 20471 test framework.
This product page lists chromaticity & luminance factor values and colorfastness to light Grade 4, which are useful checkpoints for buyers building a certified garment pipeline.

Key Performance Highlights

• Hi-Vis Yellow background material positioning for PPE visibility programs

• Waterproof-breathable TPU bonded structure with a milky (white) backing (clean inside appearance)

• 10,000mm water pressure rating for strong rain protection

• RET < 15 breathability indicator (high comfort tier in common EN 343 class tables)

• Colorfastness to light: Grade 4

• Documentable color metrics: β (luminance factor), x/y chromaticity (as listed on the product page)

Technical Specifications

Chromaticity & Luminance Factor (as listed): β / x / y values are shown on the page for the hi-vis yellow background material.

Standards & Compliance Notes

EN ISO 20471 (High Visibility Clothing)

EN ISO 20471 is a high-visibility clothing standard for enhanced conspicuity, with requirements covering garment design, background material performance, and reflective material performance. Test labs note that background (fluorescent) material is evaluated for color/luminance (chromaticity & luminance factor) and durability performance in the EN ISO 20471 framework.

Important: EN ISO 20471 is ultimately a garment-level certification. Fabric data helps your development and pre-checks, but final approval depends on garment design (coverage area), reflective tape layout, and system testing.

EN 343 (Protection Against Rain)

EN 343 evaluates protection against rain and foul weather by looking at water penetration resistance and water vapour resistance (RET)—then assigning performance classes. Many guides show Ret ≤ 15 as Class 4 breathability (best), and Class 4 as the highest waterproofness tier.
This product is positioned as EN 343 4:4 and lists RET < 15 plus 10,000mm waterproof performance.

Best-Fit Applications

Hi-Vis rainwear & waterproof workwear shells

• Rain jackets, over-trousers, waterproof outer shells

• High-visibility PPE for logistics, roadwork, municipal services
  (Usage includes workwear / PPE / rainwear on the product page.)

Industrial PPE programs that demand comfort during activity

If your customers complain about “sweaty rain gear,” the RET < 15 positioning is a strong selling point for higher-tier comfort while still maintaining waterproof protection.

Color-critical projects (visibility programs)

Because some job sites require specific hi-vis colors—and some rail environments may restrict colors—buyers should confirm their end-user policy early.

OEM / Program Support

To convert high-quality B2B visitors, it helps to make your sourcing workflow easy. Typical “brand buyer” needs include:

• Shade control & lot consistency: lab dip → bulk standard → lot tracking

• Pre-production sample meters: for seam construction, tape trials, wash/aging checks

• Documentation pack: TDS + key test items aligned with your EN ISO 20471 / EN 343 route

• Roll packing & labeling as per factory cutting requirements

• Lead time planning: standard production time is listed as 10–15 days after sample confirmation (project timing depends on order size and color).

FAQ

1) Is this fabric “EN ISO 20471 certified”?
EN ISO 20471 is a garment standard. Fabric color/luminance performance is part of the system, and this page lists chromaticity/luminance factor data, but final certification depends on the finished garment design and testing.

2) What does EN 343 4:4 mean?
EN 343 commonly reports water penetration class : breathability class. Many workwear guides list Class 4 as the highest tier for both waterproofness and breathability, with breathability Class 4 corresponding to Ret ≤ 15.
This product page lists EN 343 4:4 and RET < 15.

3) What does “10,000mm waterproof” mean for real use?
It’s a hydrostatic head / water pressure rating used to compare water resistance. Final garment waterproofness also depends on seams, closures, and construction (and whether seam sealing is used).

4) What is “TPU milky coating / TPU bonded”?
The page describes the finishing as TPU bonded with waterproof-breathable performance and a milky (white) backing. This typically provides a clean inside appearance and engineered water resistance.

5) What are the standard specs (weight/width/construction)?
190 gsm, 150 cm width, 300D*300D, density 23×19, 100% polyester (as listed).

6) What is colorfastness to light for this fabric?
The page lists Colorfastness to light: Grade 4.

7) How is it packed and what’s the production lead time?
Packing: by roll or per client requirement. Production time: 10–15 days after sample confirmation (as listed).

8) Can you support bulk brand programs (shade control and repeat orders)?
Yes—share your shade reference and yearly volume, and we can propose a lot control and sampling plan.
