Good for you, good for the planet

We chose to use TENCEL™ modal, produced by industry leaders LENZING™. Lenzing are based in Austria and have created world class environmental practices.

Modal fibres are produced from dissolving pulp in a multi-stage process using sustainably produced wood – and manufactured as environmentally friendly as possible.

Throughout LENZING's closed loop production process waste gases do not burden the environment but are recovered, converted and returned to the production process to be used as raw materials.
