The shirt is also known for its remarkably soft, breathable, and moisture-wicking fabric composition, thanks to the use of Lyocell. Lyocell, a fabric manufactured by Lenzing, uses a resource-conserving, circular process in Austria, consuming 80% less water compared to the production of cotton. This shirt aligns with the brand's commitment to sustainability by using 100% Tencel from Lenzing for the fabric, 100% Tencel from Lenzing for the sewing thread, and 100% organic cotton for the label. Furthermore, this product contributes to the protection of the environment by avoiding the release of microplastics with each wash.

The fabric for this product is sourced from Portugal, while the Lyocell yarn (Tencel) is sourced from Lenzing in Austria. The sewing thread is also derived from Portugal, and the labels are sourced from Germany.
