The PIONEER V1053060U-5XL is a hi-visibility cooling safety shirt designed for trade professionals working in hot, demanding outdoor or industrial environments. Built with 37.5 Technology, the fabric uses permanently embedded natural volcanic minerals to pull heat and moisture away from the body before sweat accumulates. The result is a shirt that actively helps the body thermoregulate, reducing heat stress during extended shifts. Sized at 5X-Large in hi-vis yellow, this shirt is a practical choice for HVAC techs, plumbers, electricians, and other field trades who require both comfort and job-site visibility.
This cooling safety shirt is suited for outdoor and industrial work environments where heat management and high-visibility compliance are both required. The hi-vis yellow color and StarTech reflective tape make the shirt appropriate for road-side work zones, construction sites, and utility corridors where workers must remain visible to equipment operators and passing traffic. The 37.5 Technology fabric is engineered to maintain comfort across varying temperatures, making it functional across a wide range of seasonal conditions and work settings.
Designed as a general-purpose hi-visibility cooling safety shirt suitable for field trades requiring ANSI-compliant high-visibility outerwear in warm or hot working conditions.
No tools or mechanical installation required. Follow applicable worksite PPE and hi-visibility garment requirements, including ANSI/ISEA 107 standards where mandated by the job site or contractor. Launder according to garment care instructions to preserve reflective tape performance and fabric technology over time.
