BNWT Color: Undyed Stone 100% cashmere. Mongolian cashmere. Undyed stone is just as it sounds—undyed. The natural color of goat hair is spun directly into the yarn with zero dye, a process that not only uses fewer chemicals, but also saves water, electricity, and CO. Lightweight super-soft knit with an eco-friendly twist. Faux-horn buttons. Dry clean. Oversized fit. In our search for sustainable fabrics that make uniform necessities better for both your wardrobe and the planet, we landed on undyed cashmere—an eco-friendly alternative to knits that just so happen to work within our favorite neutral color range. A dramatically oversized body and the perfect relaxed fit make it ideal for layering. Trust us when we say: you'll never want to take this off.
