Calvin Klein taps Ananas Anam and TENCEL for sustainable knit trainer

In London, household name designer Calvin Klein is using fibers from pineapple and wood wastes in its debut trainer footwear.

“The Sustainable Knit Trainer” features a knitted upper composed of Ananas Anam’s PIÑAYARN® blended with Lenzing’s TENCEL™ Lyocell fibers. Crafted through a low-impact manufacturing process, PIÑAYARN® harnesses the potential of pineapple leaf waste while employing a water-free spinning technique. The inclusion of TENCEL™ Lyocell, a fiber sourced from responsibly managed forests and produced through a solvent spinning process with a remarkable solvent and water recycling rate of over 99%, ensures complete traceability of TENCEL™ fibers within the blended yarn.

The casual shoe is available in in classic hues, including black and off-white, with the iconic Calvin Klein logo.
