The Balderus Jacket is a technical fleece built for sustained effort in cool mountain environments. Constructed from Wuru® — a recycled Italian wool blend of 46% wool, 35% polyester, and 16% polyamide — the fabric delivers warmth and durability in a knitted fleece format. Reinforced nylon sections at high-wear zones add wind protection and longevity, while a raglan cut keeps the jacket stable during dynamic movement. A two-way front zipper allows ventilation control as the pace changes, and an internal drawstring hem lets you dial in fit against the elements.
