Portwest BZ14 Navy Iona Bizweld Trousers

Bizweld is the ideal fabric for withstanding hazards such as molten iron and radiant heat, while garments from the Iona range are guaranteed to increase your visibility in dingy conditions. The Portwest BZ14 Navy Iona Bizweld Trousers combine the benefits of these two collections, with an impressive set of protective standards as well as the characteristic stripes of high-vis tape on both legs.

What Can the Navy Iona Bizweld Trousers Do for Me?

The trousers have several helpful features:
