Making clothing can be a dirty business, but we strive to keep it clean. Our line is crafted for quality and long-term performance. And we limit what we make: small-batch production ensures every garment is built to the highest standards and finds a loving home. Our approach minimizes landfill waste and uses less energy and water. We know it’s disappointing when a style you love is out of stock, but we appreciate your joining us in our pursuit of the highest environmental standards and carbon neutral impact.

"Sadly, this item didn't work for me. The sizing was smaller than expected, it fit like underwear and was tight in the chest and the arms. I was wanting a more relaxed fit. The fabric was soft, but still too itchy for my sensitive skin, especially because the tight fit means I can't wear a layer underneath. I am returning this item."
