When heat and high-pressure combine, it can test your limits. To perform your duties, you need a garment that can integrate your uniform, or be comfortable and professional-looking enough to be worn as a stand alone shirt. The 37.5 Hybrid Patrol Shirt does just that and offers up to 5X more cooling than any other performance technology on the market today. Remain cooler and drier as the 37.5 technology regulates your body's micro climate by evaporating moisture, helping you sweat less.
