As its most sustainably designed collection, denim giant Levi's calls its Wellthread line. Within the spring/summer 2022 collection, the whole thing is set to evolve and become more about natural and plant-based dyes, particularly plant-based indigo, as well as greater use of organic cotton and rainwater-irrigated hemp.

According to Levi's, each garment is dyed with natural and plant-based dyes that do not use resources from the food industry or raw materials that are endangered in any way. The natural, plant-derived indigo dye, which is designed to reduce the use of chemicals and water in the dyeing and finishing process, is used in several denim styles – including the Wellthread Trucker, 551 Z and Stay Loose jeans for men, and the High Loose jeans and shorts for women – and is said by Levi's to meet the highest standards (green) of screened-chemistry practices for apparel production, meaning only the most environmentally sound chemicals are used in each case.

The biggest innovation in materials this season, the company said, is the increased use of European rainwater-irrigated hemp, both in Cottonized Hemp and in a blend of cotton and hemp. In several styles – including the Levi's Wellthread Trucker, the Wellthread 551 Z for men and the Wellthread High Loose Jeans for women – the rainwater-irrigated hemp was left undyed, in its natural, raw form. This gives it a warm color that resembles linen. In addition to hemp, each T-shirt and hoodie is made from organic cotton.

Moreover, Levi's wants to pay attention to fair working conditions as part of Wellthread: all styles are made in a factory that has implemented the Worker Well-Being Initiative. This aims to ensure a safe working environment and fair pay for all workers in the supply chain.

"Wellthread makes great strides every season. And while not every season can be revolutionary, there is constant evolution. This is one of those seasons for which ideas have matured and been refined. Such as the introduction of vegetable indigo. [...] This is an example of how a good idea gets even better when we take a few seasons to develop and refine it," says Paul Dillinger, VP, head of global product innovation, Levi Strauss & Co.
