The Yoko Hi-Vis Long Sleeve T-Shirt delivers class 3 certified visibility with enhanced comfort engineering for comprehensive high-visibility workwear programmes. Compliant with EN ISO 20471: 2013 + A1: 2016 class 3 and RIS-3279-TOM standards (orange colourway), this t-shirt ensures maximum visibility in low-light and adverse conditions. The soft ribbed knit collar and cuffs provide comfort against the skin whilst resisting curling and maintaining structural integrity through repeated wear and laundering. A taped neck eliminates irritation and enhances comfort during extended wear, prioritising genuine wearability without compromising safety standards. Comprehensive reflective banding—positioned around the body, across both sleeves, and over each shoulder—ensures 360-degree visibility essential for workers in traffic-adjacent or industrial environments. The strategic placement of reflective bands maximises visibility from all angles, particularly important for roles requiring consistent awareness during movement and from multiple directions. Twin needle hem reinforces the garment's lower edge, enhancing durability and preventing seam separation through repeated washing and active wear. The long sleeve design provides additional sun protection and thermal coverage for extended outdoor work, making this t-shirt suitable across seasons and varied weather conditions. This long sleeve t-shirt represents a sophisticated approach to high-visibility workwear, merging certified safety excellence with genuine comfort and practical durability, making it an essential foundation piece for organisations prioritising worker protection across demanding work environments.
