Radians ST31-3PGS Long Sleeve Cooling T-Shirt: Class 3 Hi-Vis Protection That Beats the Heat

Radians ST31-3PGS Long Sleeve Cooling T-Shirt: Class 3 Hi-Vis Protection That Beats the Heat

High-visibility compliance and heat stress prevention are often treated as competing priorities on active jobsites. Long sleeves are required for sun protection and visibility, yet traditional garments can trap heat and discourage PPE compliance. The Radians ST31-3PGS Long Sleeve Cooling T-Shirt Max-Dri Class 3 Hi-Vis Green bridges that gap by combining ANSI Class 3 visibility with advanced moisture-wicking and cooling fabric technology. Designed for construction crews, roadway workers, utilities, and industrial teams, this cooling T-shirt delivers all-day comfort while maintaining the highest level of high-visibility protection.

1. Why Class 3 Hi-Vis Apparel Matters

Class 3 is the highest visibility level defined by ANSI/ISEA 107 and is required in environments with high-speed traffic, complex backgrounds, or reduced visibility.

• Maximum coverage: Long sleeves and full-torso coverage increase visual recognition.
• Enhanced struck-by protection: Critical for road crews, flaggers, and utility workers.
• Regulatory confidence: Meets strict visibility requirements for demanding environments.

2. Cooling Technology Built for Hot Conditions

Radians’ Max-Dri fabric is engineered to manage moisture and promote evaporative cooling throughout the workday.

• Moisture-wicking fibers: Pull sweat away from the skin to speed evaporation.
• Lightweight construction: Reduces heat buildup compared to traditional cotton shirts.
• Quick-dry performance: Helps maintain comfort during long, physically demanding shifts.

3. Long Sleeve Design for UV and Skin Protection

Long sleeves play a key role in protecting workers from ultraviolet (UV) exposure and minor abrasions.

• Sun protection: Shields arms from prolonged UV exposure during outdoor work.
• Reduced skin irritation: Helps prevent cuts, scrapes, and contact irritation.
• All-season versatility: Suitable for hot weather when made with breathable fabrics.

4.Enhanced Design Features That Support Visibility and Comfort

The Radians ST31-3PGS Long Sleeve Cooling T-Shirt is engineered with practical, jobsite-ready features that enhance visibility, comfort, and durability in demanding outdoor environments.

• 2" Heat Transfer Segmented Reflective Tape: Provides high visibility without restricting movement, improving comfort during long shifts.
• Reflective Sleeve Striping: Two horizontal reflective stripes on each sleeve enhance arm motion visibility, helping equipment operators and drivers recognize worker movement.
• Upper Left Front Pocket: Convenient chest pocket allows quick access to small tools, notepads, or job credentials.
• Mesh Side-Seam Inserts: Improves airflow and breathability, helping release trapped heat during high-exertion tasks.
• High Visibility Green Fabric: Maximizes daytime visibility and meets ANSI color contrast requirements for roadway and industrial work zones.
• 25-Wash Durability Rating: Designed to maintain visibility, fit, and cooling performance through repeated laundering.
• ANSI/ISEA 107 Compliance: Meets Class 3 visibility standards, making it suitable for high-speed traffic and complex jobsite environments.

5. Comfort Drives PPE Compliance

Workers are more likely to wear required PPE when it is comfortable and breathable.

The ST31-3PGS is designed with a relaxed athletic fit that allows full range of motion without clinging or restricting movement. Flat seams and lightweight fabric reduce chafing, making it easier for workers to keep the shirt on throughout long shifts—supporting consistent compliance with hi-vis requirements.

6. Ideal Applications Across Industries

This cooling hi-vis shirt is well-suited for environments where heat, sun exposure, and visibility hazards overlap.

• Roadway and traffic control: High-speed vehicle environments requiring Class 3 apparel.
• Construction and utilities: Outdoor work with prolonged sun and heat exposure.
• Warehousing yards and logistics: Visibility around moving equipment and vehicles.

7. Easy Care and Long-Term Use

PPE that is difficult to maintain often gets replaced prematurely or ignored.

The Radians ST31-3PGS is machine washable and designed to retain moisture-wicking and visibility performance over repeated wash cycles. Proper care helps extend garment life while maintaining compliance and comfort.

Bonus Tip:
Issue multiple cooling shirts per worker so garments can be rotated and fully dried between shifts, improving hygiene and comfort.
