Portwest ES1 Essential Hi-Vis Mesh Executive Vest

For professionals who need more from their hi-vis vest than basic visibility, the Portwest ES376 ES1 Essential Hi-Vis Mesh Executive Vest sets a new standard in workwear functionality. Combining advanced MeshAir cooling technology with a comprehensive suite of executive features — multiple pockets, dual ID display, radio loop, D-ring, and zip fastening — the ES376 is engineered for site managers, supervisors, rail operatives, and client-facing professionals who demand performance, practicality, and a polished appearance in equal measure.

Constructed from MeshAir — a 100% polyester mesh fabric at 150g — the ES376 is purpose-built for warm weather and high-activity working environments. The open mesh structure promotes exceptional airflow across the torso, keeping the wearer noticeably cooler and more comfortable than standard woven or knitted hi-vis fabrics. Crucially, the MeshAir fabric is fully EN ISO 20471 compliant in its own right — meaning the ventilation benefits come without any compromise to certified visibility performance.

Six Pockets — Every Essential Within Reach

The ES376 has been designed to replace the need for additional pouches, holders, and clip-on accessories with a fully integrated storage and accessory solution. The six-pocket layout covers every professional requirement:

• 2 lower patch pockets for documents, phones, and everyday essentials
• 1 dedicated pen pocket for quick access writing tools
• Dual ID holder allowing simultaneous display of both portrait and landscape ID cards — ideal for professionals who carry multiple forms of identification or accreditation
• D-ring for secure attachment of keys, ID lanyards, or access cards
• Radio loop for convenient clipping and carrying of two-way radios — an essential feature for site managers, security operatives, and rail workers who rely on constant communication

Everything has a place, and everything is accessible — reducing time spent searching pockets and keeping your focus where it belongs.

Front Zip for Fast, Professional Access

The full-length front zip opening gives the ES376 a cleaner, more executive appearance than hook and loop closure vests, and provides easy on and off access throughout the working day. The zip fastening also offers a more secure and weather-resistant closure, ensuring the vest stays in place and looks professional even during active, hands-on work.

Certified for Professional and Rail Industry Use

Despite its executive feature set, the ES376 meets the same rigorous safety standards as any professional hi-vis garment:

• EN ISO 20471 Class 2 certified — maintaining full compliance after 25 washes.
• RIS 3279-TOM Issue 2 compliant (orange colourway only) — fully approved for rail industry use.
• Fully CE certified for professional use across European work environments.
