If you're looking for personal protective equipment for your job in industrial and scientific fields, this is an excellent choice. The shirt is comfortable, reflective, and durable. Through trial and error I found that it is the perfect combination of high-visibility and breathable material.No worries about getting too hot in this shirt, even on the hottest summer day. The only downside is that it is only available in two colors. Overall, this is a great investment for those who work in potentially hazardous conditions..
