Think of it as the 5.11® Job Shirt, with added capabilities and heightened levels of comfort. The Utility Job Shirt was engineered working side-by-side with emergency services professionals from around the world. With their input, we started with the popular features of our Job Shirt, and updated it with a new fabric blend. Crafted from 7.8 oz. 60/40 cotton/poly fleece, the Utility Job Shirt is the perfect combination of all-weather warmth and breathability.
