Polyviscose is a blended fabric made from polyester and viscose fibers, designed to replicate the look of traditional wool tartan while offering easier care and lower cost. It is commonly used in kilts because it holds color well, resists wrinkling, and requires less maintenance than wool, making it suitable for everyday wear. While it does not have the same weight or natural feel as wool, polyviscose can still maintain pleats and provide a similar visual appearance. Its lighter weight and durability make it a popular alternative for modern and entry-level kilts.
