The KÜHL Airspeed Long Sleeve Shirt in Dusk Blue is a lightweight performance button-down designed for active comfort and outdoor versatility. Constructed from three premium fabric panels — a woven nylon/polyester body for durability and UPF 30+ sun protection, knit polyester/cotton panels for stretch, and mesh polyester/cotton for breathability — it offers quick-drying comfort and airflow ideal for hiking or travel. Features include a hidden button-down collar, button-front closure, secure zippered chest pockets, roll-up sleeves with button tabs, and built-in sunglass cleaner. The regular fit and hip-length cut make it easy to wear solo or layered, while the Feather Grey color balances performance with everyday style.
