The Portwest ES303 ES1 Essential Hi-Vis Sweatshirt is a high-visibility layer for cooler days when you need more warmth than a T-shirt. It keeps you visible on site and in other places where being seen matters.
The knitted fabric has a brushed backing that feels soft against the skin. Reflective tape helps you stay visible in low light, and the fabric also gives sun protection when you work outdoors.
