Pioneer V1053060U-4XL Cooling Safety Shirt 4XL Hi-vis

Product Description

The PIONEER V1053060U-4XL is a hi-vis cooling safety shirt built for trade professionals working in demanding outdoor or industrial environments. Sized at 4X-Large and offered in high-visibility yellow, this shirt integrates 37.5 Technology, which embeds natural volcanic minerals permanently into the fabric. These minerals work continuously to remove heat and moisture from the body, helping to maintain a stable core temperature during heavy exertion. The result is a garment that supports natural thermoregulation without reliance on external cooling devices. It is designed for HVAC technicians, electricians, plumbers, and other field trades who need compliant high-visibility workwear that also manages heat and sweat on the job.

This shirt is suited for residential and commercial jobsite use where high-visibility PPE is required by site safety standards. The ribbed crew neck construction and reflective tape placement make it appropriate for road-adjacent work, utility sites, and construction environments. The faster drying time and increased breathability address the practical demands of techs who wear their workwear through full shifts in warm or humid conditions. It functions as everyday hi-vis workwear with built-in thermal and moisture management.

Installation Notes

No installation is required for this garment. Follow jobsite PPE policies and applicable ANSI or OSHA high-visibility apparel standards when selecting and wearing hi-vis workwear. Launder according to garment care instructions to preserve the integrity of the embedded 37.5 Technology minerals and reflective tape. Do not use bleach or high-heat drying cycles, as these can degrade reflective and performance fabric properties.
