When it comes to staying visible and comfortable on the job, it’s best to grab a high visibility shirt. Thick, insulating reflective clothing may be great for the winter, but not when it’s nearly 100 degrees Fahrenheit outside. Lighten your load in the field with these hi vis shirts. They’re made with moisture-wicking materials to keep the sweat away, so you can stay clean and dry all day long. They’re much lighter than other types of hi vis workwear, so you and your team can move freely without getting bogged down by extra layers.
