The Kosto AluSkin VHKA01 protective shirt is designed for foundry workers and welders exposed to multiple thermal hazards, including molten metal splashes, welding projections, heat and flame. It also provides Category 2 protection for workers at risk from electric arcs, with an ATPV of 12 cal/cm². Its lightweight AluSkin fabric blend combines the protection required for these demanding work conditions with a comfortable garment design. Back ventilation and adjustable cuffs support wearability during industrial tasks, while FR reflective tape adds visibility. The shirt can also be paired with compatible AluSkin pants when coordinated upper- and lower-body protective clothing is required.
