The perfect intersection of classic design and rugged durability. Our Heritage Field Crew is defined by its clean, timeless silhouette—featuring a structured flat hem and a soft, fleece-lined interior that provides immediate warmth without the bulk. Crafted with a 100% cotton face and tightly knit 3-end fleece, this sweatshirt is built to endure. Whether you’re navigating the limestone bluffs or enjoying a "Birds & Brews" morning at the Center, the double-needle stitched ribbing and side-seamed construction ensure this piece remains a staple in your outdoor wardrobe for years to come. Technical Features: The Fabric: A premium blend (65% cotton, 35% polyester) with a 100% cotton face for a smooth, high-quality finish. Heavyweight Comfort: 8.5 oz/y² fabric weight offers substantial insulation for the modern naturalist. Superior Build: Tightly knit 3-end fleece with double-needle stitching on the collar, cuffs, and hem for maximum longevity. Heritage Detail: Features a tonal self-fabric patch on the back for a subtle, refined touch. Important Sizing Note: To ensure the perfect fit for your active lifestyle, we recommend ordering one size larger than your usual size. This specific cut runs slightly small, and a size up will provide the ideal comfort for layering over your Heritage Tee.
