The Sierra Organic T-Shirt is designed for young adventurers and made from a very special material. Yarn, better known as coffee yarn or Omnipotent COFFEE, is spun from purified and regrinded coffee grounds. This material not only has very fast-drying properties, but also naturally protects you from UV rays. If you mix the coffee yarn with organic cotton, you get a light, comfortable T-shirt that is pleasant to wear. The dashing Ayacucho logo on the front and cheerful mountain landscape on the back add a playful touch. Perfect for active days and adventures! Kids Sierra Organic T-Shirt
