What: Nike is set to release hoodies and crewnecks using its new sustainable material on September 8th.

Why it is important: Nike has famously cut down on production waste and improved manufacturing processes through its previous innovations such as Dri-Fit and Flyknit. Now, its newest fibre, Forward, could cause another shift in sportswear and garment production while reducing the company’s overall carbon footprint.

The non-woven fibres cut out some of the most carbon-intensive steps in traditional clothing production by eliminating the yarn spinning and weaving process. Similarly, to how surgical masks are created, Nike feeds a web of fibres into a machine containing a bed of needles that punch the fibres together to attach them. The resulting material is industrial and thin yet stiff creating a more rigid drape than a typical sweatshirt material.

The fabric has a higher warmth-to-weight ratio and a carbon footprint that’s 75% smaller than the brand’s comparable knits. The initial release is undyed, cutting out the water and harsh chemical used. The colour of the fabric will be influenced by the fibres fed into the machine.

While the new manufacturing process enables Nike to use a variety of recycled materials, the first release is made of 70% recycled polyester, a known polluter. Despite this, Nike has tried to offset the fibre choice by not using any zippers or extra trims, making it easier to recycle. According to Nike, the Forward fabric remains more sustainable and sheds fewer microfibres than knit fabrics also comprised of polyester.
