The satin tour jacket, drawn from the heritage of Japanese baseball. The Boston Red Sox Iconic Full-Snap Warm-Up by Fanatics is cut from a soft, lustrous satin, the kind of refined fabric that holds its shape, catches the light and earns its place in your everyday rotation. A boxy cropped silhouette with snap-front closure and stand collar takes cues from Japan's vintage satin tour jackets, paneled in color-blocked navy and white with striped rib trim at the collar, cuffs and hem. The script Boston Red Sox wordmark at the chest and the team logo on the left sleeve come in satin applique with embroidered outlines, a hallmark of vintage souvenir jackets.
