Sunbrella rain fabrics are treated with a water resistant coating applied to the back face that minimises water absorption and enables the cushion to dry out faster than standard fabrics. When wet, the fabric threads expand slightly, meaning any water beads up on the fabric surface, rather than seeping into the cushion filling and leaving behind residual moisture. Cameron Anthracite fabric contains Sunbrella recycled yarns. Due to the nature of the recycled content of these yarns, Cameron Anthracite fabric may exhibit random colour specks and shade variations. These slubs can sometimes be a contrasting colour. The colour of these yarns may vary between production batches and large sections of recycled yarns may run sporadically throughout the fabric. The presence of these recycled yarns should not be interpreted as imperfection, but as part of the character of the recycled fabric.
