The production of "virgin" wool is land and water intensive for the grazing sheep. This is then followed by a long process that requires a lot of energy, water and chemicals to turn this wool into a piece of clothing. Recycled wool however has already gone through this process which doesn't need to happen again.
Recycled wool also has relatively low impact in it's process. The wool goes through a process to sort it into colours by selecting and blending similar colours. This means that the wool doesn't need to be dyed again resulting in saving water and not using any new dyes.
Recycled wool is soft, durable, breathable, naturally stain resistant and easy to care for.
