tasc Perfomance has been a leader in innovation and reinvention of performance apparel since it was founded in 2009. They have created an amazing fabric from bamboo. Sounds like science fiction but it is just science. They take bamboo, which is certified organic and sourced from a forest certified by the Forest Stewardship Council, and reduce it to a cellulose level which they then weave into their space-aged fabric. Then they take this comfortable and high performance material and fashion it into clothes for those with active lifestyles.
