Worsted wool is the pinnacle of durable wool processing—a method that produces stronger, smoother, more durable fabric than standard woolen yarn. The process begins with selecting long-staple fibers, which are then combed to align parallel before spinning. This alignment creates a tight, smooth yarn that resists pilling and wear far better than carded wool. The result is a dense fabric that sheds water naturally, regulates temperature across a wide range of conditions, and grows more handsome with age. Worsted wool's tight construction explains why this sweater can function as outerwear in rain and snow—the fibers are packed tightly enough to create a wind-resistant barrier while maintaining breathability. It's the same wool specification the military relied on for decades, chosen not for comfort alone but for survival in harsh conditions.
