Calvin Klein x Piñayarn

The first ever shoe upper knit from pineapple leaves: CALVIN KLEIN introduces Sustainable Trainers from PIÑAYARN.

Global fashion house Calvin Klein has launched their first ever knitted shoe upper made from pineapple leaf fibres in collaboration with Ananas Anam’s PIÑAYARN®.

Calvin Klein has embraced their commitment to source more natural materials and lower their impact on the environment through using PIÑAYARN in this new Sustainable Knit Trainer.

With a low-impact manufacturing process, PIÑAYARN is derived from agricultural waste and created through a closed loop production involving a water-free spinning process, while working to the values of circular economy.

PIÑAYARN is used in the shoe upper, offering an environmentally conscious and traceable textile made from waste pineapple leaf fibres in a blend with TENCEL Lyocell, a fibre made from wood pulp obtained from sustainably managed forests.

Positive impact from Piñayarn

PIÑAYARN is created from Anam PALF® (pineapple leaf fibre by Ananas Anam) made from the leaves of the pineapple plant, a waste product of the food industry that does not use any additional land or water to grow, while also saving carbon emissions by preventing the burning of agricultural waste. Making use of the existing waste of the pineapple harvest brings positive social impact by creating new jobs in rural areas, providing an additional and diversified income stream for pineapple farming communities.

Through collaborations with global brands like Calvin Klein, Ananas Anam is able to sustain these local supply chains and accelerate the positive social impact brought to pineapple farming communities.

To build long-term alternatives to conventional textile value chains, a conscious and sustainable approach to sourcing and utilising fibre crops and agricultural residues will be essential.

The Piñayarn x Calvin Klein shoes are available in two colours Ck Black and Marshmallow, available online at
