A heritage warm-up pullover with the weight to prove it. The Boston Red Sox Iconic Quarter-Zip Sweatshirt by Fanatics is cut from our 430gsm Sideline Terry, the kind of dense, substantial cotton fabric that holds its shape, ages into character with every wear and earns its place in your cold-weather rotation. A relaxed body with a stand collar, quarter-zip and kangaroo pocket borrows from vintage training pullovers, with ribbed cuffs and a wide ribbed waistband to anchor the fit. The throwback Boston Red Sox logo at the left chest is done in soft, raised flocking, straight from a classic athletic warm-up.
