Eco-Thermal selected bamboo naturally grows in Szechuan, China. As a renewable resource, a bamboo forest regrows in 4–5 years, while a tree forest takes 60 years.

The bamboo is dried and heated at 800^∘C until it becomes bamboo charcoal.

The bamboo charcoal is further processed to be turned into micro-particles.

Ultra-fine bamboo charcoal micro-particles are embedded into cotton or polyester fiber.

The fiber is then drawn into yarn, and processed into Eco-Thermal fabrics.
