Description
Leo S04 Fremington Rail Spec Mesh Hi Vis Vest
The Leo Workwear S04 Fremington Rail Spec Hi Vis Vest is a lightweight sleeved mesh waistcoat designed for rail, infrastructure and trackside teams that need RIS-3279-TOM compliant Class 3 high visibility clothing.
Made from Leo Workwear’s EcoViz recycled polyester Airflow mesh, the Fremington is designed to increase air circulation compared with a conventional solid-fabric waistcoat. This makes it particularly useful for warmer working conditions while still providing the fluorescent and reflective coverage required for Class 3 visibility.

The S04-O combines full-length sleeves with an open mesh construction, giving workers increased visible coverage without the weight of a heavier hi vis jacket.

Rail & Visibility Compliance
- EN ISO 20471 Class 3
- RIS-3279-TOM compliant
The S04-O is specifically listed by Leo Workwear as RIS-3279-TOM compliant, making it suitable for relevant UK rail environments where orange rail-spec high visibility clothing is required.
HVW is RISQS accredited, supporting procurement confidence for rail and infrastructure buyers. RISQS accreditation applies to the supplier rather than acting as garment certification.
Always select clothing according to the applicable site rules, required visibility class and workplace risk assessment. Branding should be positioned so that it does not unnecessarily cover fluorescent material or reflective tape.
