Bamboo

Bamboo is a textile that has recently been used due to many reasons. It is easily blended with other types of fabrics such as cotton, hemp and even spandex to produces garments such as swimwear.
It is:

• Fast Growing
• Grown in diverse climates
• Re-harvested with no damage to the environment
• Grows quickly/densely 
• Minimises Co2
• Produces 35% more oxygen than normal trees
• Slows deforestation
• Biodegradable
• No pesticides needed
• Barely uses water

Although it may seem like the perfect sustainable fabric. There is one small criticism and that is it offer no uv protection and this can be seen as a hinderance when sold as a clothing garment. 

But still i believe bamboo to possibly be the MOST SUSTAINABLE FABRIC IN THE WORLD.
