Ultrasonic Heated Tunnel Vest S549
by Portwest

Cold mornings hit differently when your core stays warm. The Portwest S549 Ultrasonic Heated Tunnel Vest combines lightweight insulation with battery-powered heating technology to help workers stay comfortable in cold, windy and damp conditions. Built with carbon fibre heated panels, heat-sealed baffles and water-resistant fabric, this heated work vest delivers warmth without the bulk of heavy winter layers.
