This men's long-sleeve performance shirt is made from 100% polyester and engineered for running and outdoor training. The moisture-management fabric wicks sweat and provides UPF 50 sun protection for long sessions in bright conditions. Antimicrobial properties help reduce odor and keep the shirt feeling fresh through multiple workouts. Subtle HUK branding on the left hip and sleeve adds a clean, athletic touch while the streamlined fit promotes freedom of movement. Please note: garment colors may vary slightly depending on the manufacturer and dye lot.
