Yoko YK103 Rail Spec Hi Vis Anti-Entanglement Vest
The Yoko YK103 Rail Spec Hi Vis Vest is an orange anti-entanglement waistcoat designed for railway, underground and other working environments where quick-release garment features may be required.
Unlike a standard hi vis waistcoat, the YK103 features hook-and-loop quick-release fastening at the front, shoulders and sides. This allows the garment to release quickly if it becomes caught or snagged, making it particularly suitable for rail and operational environments where anti-entanglement clothing is specified.
RIS-3279-TOM Railway Hi Vis Vest
The YK103 is designed specifically for professional rail use and conforms to RIS-3279-TOM. Its orange fluorescent fabric and reflective tape layout also meet EN ISO 20471 Class 2 visibility requirements.
This makes the garment a strong choice for contractors, maintenance teams and other personnel looking for a compliant railway hi vis vest rather than a general-purpose orange waistcoat.
Anti-Entanglement Quick-Release Design
- Hook-and-loop front fastening
- Quick-release shoulder fastenings
- Quick-release side fastenings
- Designed to release if the garment becomes caught
- Part-elasticated rear for improved fit
- 5cm reflective tape around the body
- Reflective tape over each shoulder
- Distinctive front reflective tape layout
The YK103 also conforms to EN 510 for anti-entanglement, giving this vest a much more specialised role than a standard hi vis waistcoat.
