The Mateo Coastal Button-Down is engineered for the man who wants a refined, architectural look in high temperatures. Crafted from a highly breathable, lightweight cotton weave, this long-sleeve shirt utilizes a classic vertical stripe pattern to naturally elongate the torso and provide a sharper, tailored silhouette. Whether styled open over a basic tee for a daytime excursion or buttoned up for a resort dinner, it delivers crisp, structured styling with maximum airflow. Design Features: Elongating Vertical Stripes: Features a precision-woven vertical stripe pattern that creates a streamlined, slimming visual effect, elevating it above standard solid button-downs. Airflow-Optimized Cotton: Woven from a low-density, breathable cotton blend that prevents heat trapping, keeping you cool and dry in humid, warm-weather climates. Structured Collar Design: Built with a reinforced collar that maintains its crisp shape under a blazer but lays cleanly when worn open and relaxed. Adaptable Cuffs: Designed with easily adjustable button cuffs that roll up cleanly to the elbow, offering versatile styling and immediate temperature control. Fit & Performance: The Mateo is cut for a Tailored Slim Fit. It is designed to sit closer to the body to eliminate the "boxy" look common in traditional vacation shirts. The soft-washed fabric offers a lived-in texture right out of the package, providing natural drape and wrinkle resistance for easy travel packing. Technical Specifications: Material: Lightweight Breathable Cotton Blend. Style: Long-Sleeve Vertical Stripe Button-Down. Fit Type: Tailored Slim (See crucial sizing notice below). Care Instructions: Machine wash cold with similar colors. Hang dry naturally to maintain the integrity of the stripe pattern and prevent heat-shrinkage.
