Arch4’s vertically integrated approach to cashmere is a journey that begins and ends in the harsh, unforgiving climate of Inner Mongolia—home to the world’s finest yarns. At the heart of this process is traceability, as each piece can be traced back to the individual herder who produced it. From the delicate combing of fibers to the final binding, every step is crafted by hand with meticulous care. What truly distinguishes Arch4 is the exceptional quality of its cashmere, which is sourced from the soft undercoat of baby goats. Proudly termed The Soft Gold, this rare, resilient fiber is backed by trusted certifications, including GOTS and CCMI, alongside a firm commitment to ethical animal welfare. The collection itself embodies a refined yet relaxed aesthetic, with unisex silhouettes and colors inspired by its rich archive.
