When temperatures drop and visibility matters, the Portwest Hi-Vis Heated Tunnel Jacket S548 delivers on both fronts. This high visibility winter jacket combines intelligent heating technology with professional-grade protection, making it an excellent choice for outdoor work in challenging conditions.

Three rechargeable batteries provide 3 to 10 hours of heat per charge, and everything arrives with a charging cable ready to go.
