Unlike standard workwear garments, the fabric composition of flame resistant fabrics varies drastically, depending on purpose and region. Traditionally in Europe and America, FR garments have been thick and heavy; however, such garments in hot Australian conditions would not suffice. Blends of cheaper, less wear-resistant fibres are also commonplace. Although such garments, when new, may pass specific FR standards and achieve comparable ratings, their degradation occurs sooner, rendering the garment less safe to wear over its lifespan.
