Portwest ES1 Essential Hi-Vis Polo Shirt L/S

When the temperature rises, staying cool, dry, and visible on site shouldn't be a compromise. The Portwest ES277 ES1 Essential Hi-Vis Long Sleeve Polo Shirt is engineered to outperform the competition — delivering superior comfort, advanced moisture management, and certified high-visibility protection that lasts the life of the garment.

Constructed from a 100% polyester Bird Eye Knit fabric at 175g, the ES277 is lightweight and breathable by design, making it the go-to choice for outdoor and industrial workers facing warmer conditions. The generous, roomy fit ensures unrestricted movement throughout a full shift, while the long sleeves provide added coverage and protection without sacrificing comfort.

Advanced Moisture & Stain Management

The ES277 is treated with Texpel™ Wicking — a quality fabric finish that actively draws moisture away from the skin, accelerates drying, and aids in stain removal. Whether you're working in direct sunlight or a physically demanding environment, this advanced treatment keeps you feeling fresh, dry, and professional from start to finish. It's the kind of thoughtful detail that sets the ES277 apart from standard hi-vis polo shirts on the market.

Visibility You Can Count On

Strategically positioned reflective tape ensures you remain clearly visible to colleagues, operators, and passing traffic in low-light and reduced-visibility conditions. Paired with the high-contrast hi-vis shell fabric, the ES277 provides all-round conspicuity whether you're working at dawn, dusk, or under overcast skies.

Sun Protection from Collar to Cuff

The long sleeve design works hand-in-hand with the ES277's 40+ UPF rated fabric, which blocks 98% of harmful UV rays — providing comprehensive sun protection across the arms and upper body. For outdoor workers spending long hours in direct sunlight, this level of coverage is not just a comfort benefit, it's a genuine health safeguard.
