The scarf itself looks and feels amazing. But best of all, every item made of vicuna wool is numbered and is accompanied by a certificate of authenticity, that grants that the wool has been gathered in a respectful and sustainable manner.
Some may feel sad that conservation is promoted this way, but considering how the production of some luxury goods has a devastating impact on the environment, this seems like a better approach.
By the way, if Vicuna is too expensive for you, but still want a sustainable luxury item, look for Guanaco wool items.
