KX3 Check Flannel Shirt
KX370 by Portwest

Some work shirts are built for the catalogue. Others are built for actual work. The Portwest KX3 Check Flannel Shirt combines classic brushed cotton comfort with practical durability upgrades designed for demanding job sites and everyday wear. Made from yarn-dyed 100% cotton brushed check fabric, this long sleeve work shirt delivers warmth, breathability and a softer feel while reinforced wear zones improve long-term durability.

Unlike standard flannel shirts that wear out quickly in high-stress areas, the KX3 incorporates reinforced Kingsmill Twill shoulder and back panels to better handle repeated movement, gear carry and daily site use. The result is a work flannel that looks good but still earns its keep.
