What Our Gearhead(R) Experts Are Saying: "I grab the ACG Fly Cap for trail runs and long sunny hikes-it's lightweight, breathable, and the removable cape is clutch for keeping the back of my neck covered. The bungee fit system keeps it snug, even in wind, and when I don't need the cape, it packs down super easily in my vest pocket." Built for explorers who don't stop when the weather shifts, the Nike ACG Fly Cap delivers versatile protection in a sleek, athletic design. Its lightweight, stretchy fabric feels soft and comfortable on long days outside, while mesh side panels and cape perforations promote airflow when the sun's beating down. The removable cape shields the back of the neck from sun and wind and can button in front for added protection. When skies clear, it detaches quickly and stows away, leaving a streamlined cap that's just as ready for trail runs or mountain treks. With an adjustable bungee toggle fit and reflective ACG logo, the Fly Cap keeps us covered, cool, and seen wherever adventure leads.
