Whether layered beneath a Knox armoured shirt or worn for other active pursuits, this intelligent fabric keeps you cool, dry, and fresh – never sticky or uncomfortable – even in the most demanding conditions.

Enhanced with premium Rudolf textile technologies:

  • HYDROCOOL®: Advanced moisture control that wicks perspiration away for rapid drying and a consistently cool, fresh feel.
  • SILVERPLUS®: Innovative antibacterial protection that prevents odour build-up, maintaining freshness and extending the life of the garment.

Strategically placed die-cut ventilation zones under the arms and between the shoulder blades deliver superior airflow and temperature regulation, so you feel composed and confident, whatever your pace.

The Women’s Dual Active Long Sleeve Top offers a beautifully tailored, feminine silhouette – gently contoured through the body with curved bonded seams, and finished with refined detailing at the neckline, cuffs, and hem.  Subtle mountain-inspired print panels and understated Knox branding complete the look with quiet sophistication.

Available in Black and Light Grey, the Women’s Dual Active Base Layer combines luxury, performance, and versatility – a piece as elegant as it is technical, ready for every ride, every season, and every movement.
