The Blåkläder 3457 is a long-sleeve base garment for work in harsh conditions where heat, flame and static are part of the job. Its robust interlock fabric is made from a modacrylic, cotton and aramid blend with built-in protective properties.
Hi-vis panels help you stand out on site. A side vent, a cuffed neck and external certification labels make it a practical first layer for demanding work.
