A high-performance black long-sleeve base-layer from UK streetwear brand Corteiz, featuring distinctive neon-yellow grid-style stitching across shoulders, sleeves, and hem for bold visual contrast. The garment uses a smooth, stretchable technical fabric with a snug yet comfortable fit—ideal for layering or standalone wear. A subtle embroidered 'Corteiz' script logo sits at chest center, reinforcing brand identity without overwhelming the minimalist aesthetic. The ribbed crew neck and reinforced seams ensure durability, while the lightweight construction offers breathability for active or urban use. Designed with streetwear functionality in mind, it bridges sportswear utility and fashion-forward detailing. Perfect for daily wear, casual outings, or as a statement layer under jackets in transitional seasons. The clean silhouette pairs effortlessly with cargo pants, jeans, or track bottoms, making it a versatile staple in modern street style.
