Class 2 Economy Two-tone Vest combines protection, job-specific performance, innovation and style. Design includes ANSI-compliant polyester mesh in an eye-catching fluorescent color and 2" Level 2 ANSI-compliant reflective material set on 4-1\/2" contrasting-color background. As light diminishes, background material plays less and less of a role in maintaining conspicuity. That's when retroreflective technologies are so important to make sure workers are seen. The machine-washable mesh fabric is lightweight, weighing only 3.3 oz. Securely close with the zipper. Single inside pocket offers storage for essentials. GloWear 8229Z vest is great for road construction, utility crews, survey crews, construction, railway workers, baggage handlers, emergency response and warehousing\/distribution. Small\/medium size fits chests from 36" to 44".
