arch4 HATS

London-based organic cashmere label arch4 promotes sustainability and longevity through clean, classic design. Launched in 2017, the womenswear brand crafts luxuriously soft knitwear using innovative techniques, organic dyes, and environmentally-sound practices. Informed by architectural textures and minimalism, arch4’s slightly masculine aesthetic is at once easeful and elegant. Timeless crewneck and turtleneck sweaters are knit from the finest baby goat underfleece responsibly-sourced from the Inner Mongolian mountains. Leading the industry in sustainable textile construction, arch4’s cashmere strand is finer than the average blend at just over fifteen micron, resulting in a softer touch less likely to pill. The label’s breathable, warm cashmere proves that comfort doesn’t have to come at an environmental cost; instead, arch4’s ethical processes and earth-friendly cashmere mark a new paradigm in sustainable luxury.
