This guide outlines the performance requirements, sizing design considerations, material options, and key procurement criteria for sourcing an ANSI 107 Class 3 rain jacket, rain pants, and complete hi-vis rainwear systems at wholesale scale.

What is ANSI/ISEA 107 Class 3 Compliance?

The ANSI/ISEA 107-2020 standard (American National Standard for High-Visibility Safety Apparel) sets minimum performance requirements for high-visibility garments designed to make workers conspicuous in high-risk occupational environments.

Garments are categorized into Performance Classes (Class 1, Class 2, Class 3) and Supplemental Class E based on the required coverage area of fluorescent background fabric and retroreflective materials:

• High-Visibility Hazard Environments: Class 3 garments are intended for situations where workers require the highest level of conspicuity, such as complex work backgrounds, reduced sight distances, high task loads, or exposure to higher-speed traffic.
• Material Area Thresholds: Standard Class 3 garments require a minimum of 1,240 square inches of fluorescent background material and 310 square inches of retroreflective material.
• Smallest Size Exception: Under ANSI/ISEA 107-2020 design rules, the smallest size in a Type R Class 3 size range may incorporate a reduced minimum of 1,000 square inches of background material to accommodate garment patterns while preserving overall visibility design integrity.
• Worksite Hazard Assessment: The appropriate performance class should be selected based on a comprehensive worksite hazard assessment and applicable safety regulations, rather than traffic speed alone.

Class 2 vs. Class 3 High-Visibility Rainwear: Technical Comparison

Selecting the correct performance level for municipal tenders, contractor contracts, or retail distribution is vital for workplace safety and compliance.

*Always refer to ANSI/ISEA 107-2020 Section 6 for full sizing exception rules and layout requirements.

Technical & Manufacturing Considerations for Class 3 Rainwear

1. Pattern Sizing & Audit Compliance Across Size Ranges

Achieving Class 3 compliance on larger sizes (L through 5XL) is straightforward due to the available fabric area. However, engineering smaller sizes (such as Size XS and S) requires precise pattern grading so that the required background area and 2-inch retroreflective striping fit without compromising garment fit or safety compliance.

At Puraingear, our high-visibility garments—including styles DL1152 and DL1153—are designed with scaled tape layouts and pocket placements to ensure design compliance across the entire size gradient, from Size XS to large adult sizes.

2. Dual-Hazard Capabilities: High Visibility + Flame Resistance (FR)

In petrochemical, utility, and industrial job sites, high-visibility rainwear must often combine waterproof performance with flame-retardant properties.

• Fabric Composition: Formulations such as 40% PU coating + 60% polyester engineered with FR treatments allow the finished outerwear to deliver dual protection: hydrostatic waterproof performance alongside flame-resistance compliance.
• Testing Standards: Dual-hazard rainwear should be tested against applicable flame-resistance standards, such as ASTM D6413 (vertical flame test) or European AITEX EN ISO 14116 index standards.

Verifiable Compliance & Laboratory Evaluation Reports

Test reports should always be directly traceable to the specific manufacturer, product style, raw material specification, and tested scope. Buyers should systematically verify that documentation matches the specific garments being purchased.

What Should B2B Buyers Check Before Ordering Class 3 Rainwear?

To prevent shipping delays, compliance disputes, or tender rejections, buyers should review this 12-point procurement checklist prior to placing a bulk purchase order:

• Standard Edition: Is the garment evaluated against current ANSI/ISEA 107-2020 criteria?
• Garment Type: Is Type R (Roadway) or Type P (Public Safety) required for your target market?
• Performance Class: Is standalone Class 3 required, or a Class 2 + Class E ensemble?
• Smallest Size Validation: Has the factory submitted small sizes (XS/S) for design evaluation to confirm compliance?
• Reflective Material: Does the retroreflective material meet applicable width, area, and performance requirements, including after-care or laundering evaluations where applicable?
• Seam Construction: Are major load-bearing seams heat-taped and tested for hydrostatic pressure resistance?
• FR Compliance (if applicable): Does the fabric hold valid ASTM D6413 or EN ISO test reports?
• Traceable Documentation: Can test reports be traced directly to the specific supplier, product style, material specification, and tested scope?
• Labeling & Markings: Do garment labels provide required type, performance class, manufacturer information, care instructions, and applicable ANSI/ISEA 107 markings?
• Sample Sign-off: Has a pre-production sample been inspected for seam taping, pattern accuracy, and logo placement?
• Sourcing Parameters: Are MOQ, production lead times, and shipping terms clearly established in the agreement?
• Custom Packaging: Are OEM polybags, hangtags, and outer carton barcodes specified to meet local warehouse requirements?
