The Yoko Top Cool Open Mesh Waistcoat combines advanced thermal management with premium visibility compliance, engineered for professionals working in warm climates or high-exertion roles. The breathable lightweight mesh knitted fabric delivers exceptional airflow whilst maintaining full structural integrity and visibility effectiveness. Safety certification spans multiple international standards: ANSI/ISEA 107-2004 compliance ensures recognition across North American markets, whilst EN ISO 20471: 2013 + A1: 2016 class 2 certification provides reliable visibility for general workplace and traffic-adjacent applications. This dual-standard approach supports multinational operations and organisations requiring flexibility across jurisdictional requirements. The open mesh construction represents a sophisticated thermal solution—reflective elements remain fully functional and visible whilst the breathable fabric design significantly reduces heat accumulation and thermal stress during extended wear. This is particularly valuable for outdoor supervisors, site personnel, and operational teams working in warm-weather environments or performing physically demanding tasks where thermal comfort directly impacts safety and productivity. The tear-release front closure enables rapid removal in emergency situations, a critical safety consideration in dynamic work environments. Visibility is comprehensively addressed: dual reflective bands encircle the body with additional shoulder placement delivering 360-degree recognition from all angles. The branded tab on the left chest provides subtle space for company identification or logo placement, supporting fleet consistency and professional presentation without compromising the waistcoat's streamlined aesthetic. Ideal for outdoor operations, construction, utilities, and warm-climate applications, this waistcoat delivers certified visibility, superior thermal comfort, and practical functionality for demanding professional environments.
