The Yoko Hi-Vis Top Cool Open Mesh Executive Waistcoat combines premium visibility compliance with advanced thermal management, engineered for supervisory personnel working in warm climates or high-exertion environments. The open mesh construction maximises airflow whilst maintaining structural integrity and professional presentation. Safety certification spans multiple international standards: EN ISO 20471: 2013 + A1: 2016 class 1 and 2 compliance ensures reliable visibility across varied lighting conditions, whilst ANSI/ISEA 107-2004 certification extends application to North American markets and multinational operations. This dual-standard approach provides flexibility for organisations operating across jurisdictions with differing visibility requirements. The open mesh design delivers exceptional breathability without compromising visibility—reflective elements remain fully functional whilst allowing superior air circulation, reducing thermal stress during extended wear in warm conditions or physically demanding roles. The front zip closure provides secure fastening with rapid deployment capability. Visibility is comprehensively addressed: dual reflective bands encircle the body with additional shoulder placement for 360-degree recognition. Communication and storage features are strategically positioned for operational efficiency: a radio loop accommodates two-way communication devices, whilst the left chest media pocket with integrated pen pocket and D-ring supports equipment attachment. Dual ID pockets—one with side access on the right chest and one with top access on the left chest—provide flexible credential storage. Two front pockets with protective flaps and dual access enable convenient item retrieval. Ideal for outdoor supervisors, site managers, and operational leaders in warm-weather environments, this waistcoat delivers certified visibility, superior thermal comfort, and practical functionality for demanding industrial and infrastructure applications.
