Portwest ES1 Essential Hi-Vis Polo Shirt S/S

When the sun is out and the workload is heavy, you need a hi-vis polo shirt that works just as hard as you do. The Portwest ES477 ES1 Essential Hi-Vis Short Sleeve Polo Shirt is engineered from the ground up to outperform standard hi-vis polos — combining thoughtful design details, advanced fabric technology, and certified high-visibility protection into one exceptionally comfortable garment.

Crafted from a 100% polyester Bird Eye Knit fabric at 175g, the ES477 is lightweight, breathable, and purpose-built for warmer working conditions. The comfort fit design and generous cut give you the freedom to move naturally and work without restriction across a full shift, while the ribbed collar adds a clean, professional finish that holds its shape day after day.

Texpel™ Wicking — Engineered to Keep You Cool and Fresh

At the heart of the ES477's performance is its Texpel™ Wicking fabric finish — an advanced treatment that actively draws moisture away from the skin, accelerates drying, and makes stain removal significantly easier. On warm days and in physically demanding roles, this technology makes a tangible difference, keeping you cooler, more comfortable, and looking professional throughout your entire working day. It's the kind of detail that puts the ES477 ahead of competing hi-vis polo shirts at a similar price point.

Reflective Tape for All-Conditions Visibility

Strategically placed reflective tape ensures the ES477 keeps you visible in low-light, dawn, and dusk conditions — complementing the bold hi-vis shell to provide reliable all-round conspicuity on site. Whether you're directing traffic, working a utilities project, or operating near moving vehicles on a rail corridor, the ES477 ensures you're always clearly seen.

UV Protection Built Into Every Fibre

Working outdoors in a short sleeve garment means your arms and upper body are exposed to the elements — which is why the ES477's 40+ UPF rated fabric is such a valuable feature. Blocking 98% of harmful UV rays, it provides a meaningful layer of sun protection that helps safeguard your long-term skin health across the spring and summer months.
