While 100% cotton workwear exists, it generally does not meet EN20471 standards for high-visibility garments. The reason lies in the ability of cotton to retain bright colours after multiple washes.
For high-visibility clothing, maintaining colourfastness is crucial to ensuring compliance with safety regulations. Unfortunately, cotton tends to fade quicker, making it less suitable for long-term visibility needs.
Why is Polyester Commonly Used in Hi-Vis Workwear?
Polyester is commonly used in hi-vis garments due to its superior ability to hold vibrant colours over time, particularly under repeated washing and exposure to the elements. To meet EN20471 standards, hi-vis workwear must retain its brightness to ensure ongoing safety compliance, which polyester helps achieve. It offers durability and long-lasting colour retention, making it the material of choice for most compliant high-visibility garments.
Alternative Solutions: Bamboo-Blend Garments
For workers who find polyester uncomfortable or are sensitive to the fabric, bamboo-blend garments offer a promising alternative. Bamboo fabric has a softer feel and breathability, making it more comfortable for all-day wear while still offering the durability needed for workwear.
Leo Workwear provides great options for bamboo-blend hi-vis garments. Currently, the P01 and P05 polo shirts are the top recommendations. The bamboo in these shirts reduces the "polyester feel," making them ideal for staff who prefer a softer, more natural fabric. We recommend trialling these garments, especially for staff with fabric sensitivities or comfort concerns.
Standard Workwear Options
For those whose job roles don’t require EN20471-compliant garments, standard workwear made from 100% cotton or other natural fibres may be a suitable option. These garments are breathable and comfortable but lack the high-visibility properties needed for roles requiring compliance with visibility standards.
For teams that don't need EN20471 certification, cotton workwear can offer comfort without the need for polyester’s colour-retention qualities.
