The Ariat Western VentTEK Snap Short-Sleeve Shirt has tons of built-in advantages. First, its AriatTEK technical design and performance fabrics are ready to tackle any climate in comfort.

When it's sunny outside, this men's shirt features a UPF 40 sun protection rating to keep your skin safe from the sun's harmful rays. Best of all, Ariat's VentTEK design allows for excellent airflow to help you stay cool in the heat, and Moisture Movement Technology (MMT) adds moisture-wicking, quick-drying performance to its long list of benefits.
