"What Our Gearhead® Experts Are Saying: ""I rely on this top for long days outside when sun exposure and movement are unavoidable. The fabric stays cool and dries fast, even when I’m active, and the semi-fitted cut never feels restrictive. The thumbholes and raglan sleeves make a real difference when you’re moving your arms all day."" We pull on the Sunup Long-Sleeve Crew when the day starts early and ends late under open skies. Huk built this layer for performance-driven comfort, making it a dependable choice for everything from hours on the water to travel days that demand breathability and protection. The lightweight feel keeps us cool, while the streamlined fit layers easily or stands on its own in warm conditions. Designed with movement in mind, the raglan sleeves and gusseted armholes allow a full, unrestricted range of motion, while flatlock seams help prevent chafing during long wear. Moisture-wicking fabric keeps sweat in check, and built-in UPF 50 protection plus thumbholes provide added coverage when the sun is relentless. Comfortable, functional, and purpose-built, this crew is made for days spent outside doing what we love."
