Weldas COOL FR™ 31-1300 long-sleeve protective shirt
The COOL FR™ line is an advanced protective clothing system designed as the first, fundamental layer of safety for welders working in high temperatures.

COOL FR™ is a smart solution that makes an ideal base for multi-layer protection systems and improves hygiene and comfort under heavier leather clothing.

Technical Details and Certification
Materials and Construction
The comfort and safety of the COOL FR™ shirt come from a specialised flame-retardant cotton with a weight of 9 oz. (approx. 255 g/m²). The material is not only light and airy but also treated for durable flame resistance, confirmed by tests over 50 wash cycles (according to ASTM D6413). The name "COOL" refers to the passive cooling effect of the low fabric weight, its very good breathability and an ergonomic cut that does not restrict movement. This is technical underwear that actively manages the welder's thermal comfort and forms a smart protective barrier directly on the skin.
Safety and Certification
The 31-1300 shirt is certified personal protective equipment that meets strict European standards. Compliance with EN ISO 11612 ensures protection against brief contact with flame and against convective and radiant heat. A key advantage is certification to EN 1149-5, which confirms the antistatic properties of the material. This means the shirt safely dissipates electrostatic charges and minimises the risk of an incendive spark in explosive atmospheres (ATEX zones). With this product you get protection confirmed by independent certification bodies.
