Yellow Hi Vis Polo Shirt P104 — EN ISO 20471 Class 2 Short Sleeve

Why the P104 Yellow Hi Vis Polo Shirt Is Built for the Demands of UK Site Work

The P104 is a yellow hi vis polo shirt designed for workers who need reliable high visibility protection and all-day breathability without the bulk of a jacket. Certified to EN ISO 20471 Class 2, it makes the wearer visible from all angles in both daylight and low-light conditions — meeting the safety standards required across most UK construction sites, warehouse environments, and outdoor working roles. From £11.99, it is one of the most affordable certified hi-vis polo shirts on the UK market.

Key Features:

• EN ISO 20471 Class 2 Certified — Fluorescent yellow background material and retroreflective tape positioned across the chest and shoulders meet the high visibility safety standards required on most UK construction sites, warehousing operations, and outdoor working environments.
• High Visibility Fluorescent Yellow Fabric — The fluorescent material delivers intense daytime visibility that makes the wearer immediately conspicuous to vehicle operators, site plant, and passing traffic without needing an additional vest layer & upf 40+ and also provide the uv protection.
• Moisture-Wicking Breathable Fabric — Polyester mix construction pulls sweat away from the skin and dries quickly, keeping you cool and comfortable through physically demanding outdoor and indoor shifts — a key advantage over heavier hi-vis t-shirts and polo shirts with non-wicking fabrics.
• Hi-Vis Short Sleeve Cut — Open sleeves maximise airflow during warm site work and active indoor roles. The short sleeve design reduces heat build-up without sacrificing EN ISO 20471 certification.
• Retroreflective Tape on Chest and Shoulders — Reflective tape is positioned to the EN ISO 20471 standard for 360° visibility, ensuring the wearer is clearly identified by vehicle operators and machinery at distance and in low-light or dusk conditions.
• Three-Button Placket with Structured Collar — Smarter, more professional presentation than a basic hi-vis t-shirt. Suitable for client-facing site visits, supervisory roles, and everyday site duties without changing garments.
• Regular Fit, Sizes S–2XL — Wash at 40°C — Comfortable as a standalone top or over a base layer. Machine washable at 40°C. Do not bleach, tumble dry, iron, or dry clean. Line dry to preserve reflective tape and fluorescent material integrity.
