The PIONEER V1053060U-L is a hi-visibility cooling safety shirt built for trade professionals working in hot, physically demanding environments. Constructed with 37.5 Technology fabric, it uses permanently embedded natural volcanic minerals to pull heat and moisture away from the body before sweat even forms. The result is a shirt that actively helps the body thermoregulate — cooling when conditions are hot and retaining warmth when they are cold. A ribbed crew neck and StarTech reflective tape round out the design, making this a functional piece of workwear suited for outdoor and industrial job sites.
This shirt is sized Large and finished in hi-vis yellow, meeting the visibility demands of road crews, utility workers, HVAC technicians, electricians, plumbers, and other trade professionals who work near traffic or in low-light conditions. The reflective tape provides passive visibility in dim or nighttime conditions without additional gear. The moisture-managing fabric reduces discomfort during extended shifts in heat-intensive environments such as rooftops, mechanical rooms, crawlspaces, and outdoor worksites.
Designed as a general-purpose cooling safety shirt for trade and industrial professionals requiring hi-visibility workwear in Large sizing.
No installation required. Launder according to the care label instructions to preserve the embedded 37.5 Technology mineral treatment and reflective tape adhesion. Inspect reflective tape before each use to confirm visibility performance meets applicable jobsite safety requirements.
