This High Visibility Safety Shirt is ANSI Class 2 Compliant. Made with lightweight 6oz Jersey Knit Polyester, it has a cotton-like feel. The performance fabric wicks away moisture 3 times faster than cotton. In addition, the 3M™ Scotchlite™ Reflective Material 5510 Comfort Trim adds extra comfort and does not buckle or rub like sewn on reflective tape.
