Get ready for cooler weather with this classic crew neck sweatshirt. This piece is crafted with pre-shrunk fabric, a 1x1 rib-knit collar with spandex, air-jet spun yarn for softness and reduced pilling, and double-needle stitching around the collar, shoulders, armholes, cuffs, and hem. The garment is quarter-turned to prevent a crease down the middle.
